Now 5 stars after 10 mos of trouble-free use - very solid performer and great bang for the buck!
UPDATED MAR 2020 - Ran new benchmarks with Sony MRW-E90 reader using CrystalDiskMark v7.0.0 x64 (5 iterations @ 1GiB) and got even better results than last time for SEQ1M (247.47 Read / 103.6 Write - see updated attached screenshots). This first test was using my Dell S2716DG as an USB 3.0 Hub. The next test was directly connected to USB3.1 port on my Aurora R7 and I got even better results (260.2 Read / 104.2 Write).
Have used this on a near weekly basis to record 4K @ 60mps with Sony A6400 (about 2hrs each session) and have not run into any issues whatsoever. At current price of $30.59, this is a true bargain and a very solid performer.
Original review from May 2019 below.
=======
Was a little apprehensive of investing further in Lexar given their recent change of ownership and then being MIA for a short period but it looks like they're finally back in business. I had initially purchased the Freetail Evoke Pro (https://www.amazon.com/FreeTail-Evoke-1000x-UHS-II-FTSD128A10/dp/B074PVQJR1) but glad I found this one as it bests the former card in performance for nearly half the price (EDIT: I purchased this in early May for $39.99 but I see the price has gone up now).
Check my attached pics for benchmarks which includes Crystal Disk 1GB 5 iterations and also actual Windows 10 copy to/from speeds. Also used it on A6400 and recorded about 1.5hrs straight at 4k 60mbps without any issues. Only thing that remains is to see how it holds up in the long so will edit this review in the future if any changes.

Great Bang for Buck UHS-II Card for Nikon D500
Currently, this is the cheapest "Name Brand" UHS-II card available on Amazon (though the Lexar brand was sold to a Chinese company for a number of years now). Current state of the art is 300 mb/s V90 cards, but those are almost 4x the price as of July 2019, compared to this 250mb/s V60 card.
Lexar had published their test results using a Nikon D500 and UHS-II card lineup, and the 300 mb/s card is able to achieve something over 50 shots before hitting the buffer (14 bit uncompressed raw). There are no direct comparisons for this card but Lexar's speeds are more or less accurate; you can probably guesstimate that this card will perform at 75% of the performance of the 300 mb/s card.
---------------------------------
Edit: As was pointed out in the comments, the 300 mb/s vs. 250 mb/s cards are referred to by their read speeds. A more accurate indicator is their write speeds, which is much lower for this card compared to Lexar's 2000x card at only 80 mb/s. Maximum performance of the car is dependent on the device you are putting this in. I'm only speaking in context of the Nikon D500.
To verify exact percentage of performance difference between a Lexar 2000x card vs. this one, I shot my D500 back to back with a Lexar 2000x vs. this 1667 card (RAW+JPEG, 14 bit uncompressed) for 30 seconds each. On the 2000x I got 102 shots. On the 1667x I got 69 shots. So it's more like 68% rather than 75% estimated performance.
---------------------------------
As others have already posted benchmark speeds for this card, I'll just focus on real world usage with a Nikon D500. Recently I bought the card for use on an Alaska cruise, so I needed to shoot bursts without hitting the buffer limit as the wildlife (whales especially) were often in a blink and you'll miss it type scenario. With a UHS-I card (Sandisk Extreme Plus 80mb/s) I used two 12 shot bursts with similar pause in between and the camera started to chug on the next burst of images- so I relegated that card to portraits only. With the Lexar, the longest burst that I used was 23 images at a time; this was in the middle of a sequence where I shot 8, 23, 12, and then another 12 photos with maybe a up to 5 second pause in between shots. Despite this, I never had to wait for the camera's buffer to clear. This was good enough for me- if I wanted even faster speeds, I'd probably just make the jump to XQD.

High Speed High Capacity Raw and 4K Shooting
I purchased two 128 GB cards and a 64 GB card. They arrived in the mail today and I tested them with high speed shooting at 46 megapixels in raw with a Nikon D850 and shot 4K video with a Panasonic Lumix SX100. I observed no lag shooting in raw with the Nikon D850 or the 4K video with the Lumix. Using a USB 3.0 card reader I downloaded the images to a desktop computer and an iPad Pro. Downloads were very fast. I was especially surprised at how fast the 4K video downloaded to the iPad Pro. Earlier earlier this year I purchased a Sony 128 GB card with 260 MB/sec read and 100 MB/sec write specs an paid twice as much. I have never had any problems using a Lexar card and consider this to be an excellent purchase.

good performance
Be aware!
I bought this card for my Sony A7r2 and realized my camera only has UHS-I type slot. This is a UHS-II card which have 2 rows of contact pins to implement higher speed transfer standard. It does work with UHS-I slot, but the performance is limited by only activating the first row pins.
I tested it will my Sandisk Extreme pro 32g, the Laxar 1667X writes about 3~5 seconds faster than the Sandisk when I brushed 10 photos in Raw(~30s vs ~25s).
Be sure your device is compatible, it works best in uhs-ii slots. I may go for the newer verson of the Sandisk extreme pro w/ 170m/s read 90m/s write in uhs-i if I noticed the problem earler

Solid performing and reliable SD card for the money
I bought a couple of these cards in the 64 GB version in early summer 2019 for use in my (then) new Sony A7III and I have another used in my Sony A7RII. Cumulatively, the cards have around 30,000 snaps with no problems of any kind.
Though (or maybe because) I don't do the sort of photography that requires me shoots RAW bursts, I've never had a problem with the card's read and write speeds. After reading several reviews here complaining about the card's read/write speed, I decided to test it myself. I did notice that the data on the card only gives read speed as 250 MB/sec, write isn't mentioned.
I'm working with a system where all the other components are much faster than the card, making it the limiting factor.
A couple or reviewers here said they think the write speed is around 45MB/sec and that agrees what I found when writing to the card both with the camera and with a data file from my computer. I shot RAW burst in continuous hi mode from my 42 MP A7RII until the buffer filled with 904 MB (22 41.4MB) raw files. The buffer cleared in 22 seconds. I also transferred at 5.7 gig file to the card from a very fast M.1 NVME through a USB 3.2 type C connection to a high speed reader and came up with 45 MB/sec almost on the nose. You can conclude that as far as write is concerned, 45MB/sec is all this card has.
I also tested the read using the same rig as above in reverse and came up with 230 MB/sec. That's pretty close to advertised.
So, the card is a slow write, so what? I've been shooting these cards for years and it hasn't bothered me a bit. But my type of shooting never needs for me to shoot 22 shots in a couple of seconds followed up with more. But some people do. If you're a sports shooter, waiting 22 seconds for the buffer to clear so you can shoot more could be catastrophe.
If you shoot portrait, street shooting, landscape, walking around a museum, you won't give a flip about 45 meg/sec write, won't ever even notice it. But if you shoot action----.
As for me, I'm gonna buy another Lexar.
BTW, don't think I've ever bought anything that's as fast as advertised. Earlier today, I was doing some backup to remote drives and managed to get a SanDisk SSD advertised at 1050 MB/second to write around 700 MB. The files were originating with a M.2 NVME on the PCie bus feeding through a USB C gen 3.2. I didn't time it but it made short work of a 65 gig file.

4K Speed is sufficient for Canon EOS-R
I bought several of these cards for my Canon EOS-R. I bench-marked the cards using my laptop and Linux.
Read speeds were on the slow side at around 92MBs per second using a sample size of 60MBs. Changing the sample size yielded the same results. Write speeds were 87.2MBs which is 5232MB per minute, which is just fine for recording 4k 29fps video with the Canon EOS-R, which requires a minimum of 3444MB per minute. A little overhead is good. This card seems to be a decent performer for the price, except for the read speeds, which most likely was related to my card reader. There faster more expensive cards for the pros, but for me these are just fine.

Very quick SD Card with 120 Mbps write speed
I bought this large capacity card for my Canon R6 to do some video captures. I couldn't find the write speed in the description, only the read speed at 250 Mbps. I took a chance knowing I would be writing large 4k video files. With Prime, I could always return it too. Upon receiving the card is when I saw confirmation that the write speed is 120 Mbps. Why they advertise the read speed so much is beyond me as you really need the write capabilities when dumping your camera buffer to disk. But I digress. I've taken a few high res 4K videos as well as some 120 fps HD video and this card had zero issues in keeping up.

Perfect for A7R3
Purchased this 128GB 1667x Lexar for use in a Sony A7R3. It was replacing a perfectly good 64GB SanDisk 300MB/s UHS-II. I just needed more space for time lapses.
I wasn’t sure if this new card would be as fast as the SanDisk since it cost 1/2 the price. Well it’s very close, and enough for my needs. I get 90-91 shots compressed RAW before the camera starts to buffer shots. The write times are close to the SanDisk albeit a bit longer.
Video works perfectly fine as well. 4K30P@100mbit no problem.
I can’t speak to the durability of this specific card but I’ve had great success with Lexar cards for many years. If this card fails I’ll update the review.
Overall I can’t recommend this card enough. Perfect for use in the Sony A7R3 in slot 1. There isn’t a better balance of speed/price for a UHS-II card that I know of. If you need the absolute best performance you’ll spend double the money for the same size and not get double the performance.

Good Speeds with Good Capacity
Purchased for recording video in 4K29.97 (and occasionally 59.94) and I get around two and a half hours of total record time (at 100Mbps) for the 30fps recording and less than that for the 60 (at 150Mbps). All in all, they don't get too hot, but like all SD cards and recording high bitrates of video/information (It can keep up with fast shutter high res image taking as well) it's going to heat up. There's no way to really avoid it but the last few times I've recorded video on previous SD cards, they've been uncomfortably hot. These seem to avoid overheating (without sacrificing my video files).
I shoot with a Lumix GH5S and it works, it's also the bare minimum for 4K, but I'm not looking to record anything higher than a 100Mbps bitrate (it can do 400Mbps in an "ALL-IN" function)

Go To SD Cards for Pro Video and Action Still Photography
I’ve been using Lexar Pro UHS 2 cards for 5 years. Even before I had a camera that makes use of the speed capacity of the UHS-2. I bought these cards specifically for my Leica SL2S. They work flawlessly on stills and video. They write faster than I can shoot.

Question & Answer
Question :
What is the write speed? only read speed in description
Answer :
Just tested this card myself. Verified 250MBps read and 120MBps write. It's actually printed on the packaging, too; just not in the product description.
Question :
Does it work with the gh5 all-i 400mb/s?
Answer :
I've bought 4 just for my gh5 camera to use it with all-i 400mb/s!!!
Well 2 works perfectly the other 2 are completely broken. After few seconds I've pressed the record button the camera stops with the error message that the card doesn't support the bitrate.
I've ordered two new cards to send back the two that are not working. So if you are lucky they works if you are not you can send them back. The card are v60 certified that means that they should support 60Mb/sec.
400mb/s = 400/8 = 50Mb/sec.!!! I think the price is great if they work!
Question :
Zoom Q2n-4k ?
Answer :
No, el Zoom Q2n usa tarjetas MICRO SD, esta es SD estandar
Question :
Is it compatible with the canon eos m50?
Answer :
Does your camera recognize UHS-II cards? If it does, it would process photos much quicker (write speed) and decrease your buffer time so you could take a greater number of photos before the buffer slows it down. You could also download photos to your computer much faster (whether your camera has UHS-II capability or not) but you would need a UHS-II card reader.
Question :
Will this work with a Canon G50 4K video camera?
Answer :
Yes, the camera uses SDXC cards. The camera doesn't support UHS-II, but the card is backwards compatible and has excellent speed for video.
Question :
Will this work on a joinlgo 4-ch gps wifi 1080p hdd mobile vehicle car mdvr video recording system?
Answer :
As for the speed it should. It works for my Sony fx6. V30 doesn’t. Just check if your device support 64 gb.
Question :
Is this card rated X-ray proof?
Answer :
If you’re asking if the card can go through airport security X-ray and not lose any data, the answer is “yes.” I’ve flown with these cards and brought them in my carry-on luggage and had no issues.
Question :
Is this compatible with a canon rebel t7/2000d eos camera?
Answer :
Yes, it is. According to specifications Canon EOS 2000D Supported Memory Card Compatibility -SD, SDHC, SDXC, and Maximum Memory Capacity 128GB
Question :
