Good product for the value. Price per storage capacity was a selling point for me personally. Overall satisfied after about 2 weeks of use.

I was able to load it in my MP3 player one time. it loaded some files from my pc and then, it froze. I tried to format it, hoping that that would help, but, nothing. It just up and died. My player would not recognize it. I put the card in the usb holder that came with the card, but the pc would not recognize it. All done!

At the steep discount price, this seemed too good to be true. Hard to tell how durable this will be when its called on to store more than 200-300 gb of data, but so far in recording lots of 4k 30fps video, its been perfect.
Using this in my Leica D-Lux7 camera, and it works fine. It certainly seems as fast as any MicroSD card that Ive used so far, but I dont expect it to be as fast as the dedicated USB-C flash drives I already own. Recommended!
i noticed my device would have problems reading on playback of 24/96 playback ~(2800K bitrate). so i put the card in my computers PCI SD slot and used H2testw to read and write test the whole card. on a short test, it seemed to do fine, 40MB/sec write and 60MB/sec read, but testing the whole card, which should have taken about 3 hours, ended up taking a whole day and ended up with the final average speeds on the card:Writing speed: 11.9 MByte/sReading speed: 11.0 MByte/swhich means some areas of the card are MUCH slower than 10MB/sec. I contacted lexar who said the card looks genuine but might be defective. Am RMA'ing with B&H and will report back
I needed a large storage of reasonable speed at affordable price. Its large OK, nearly affordable at discounted $100, but much slower than expected! With ChristalDisk I get about 20-22 GB/s (both read and write) and in real life file transfer at only 13-14. Now, my laptop is rather old and may not have a fastest card reader bay, but I get 45+GB/s with years old SunDisk Extreme 16GB small. Perhaps part of the blame may go to provided adapter, but I think its unlikely.Luckyly, I dont need speed so much for capturing 4K videos, but transferring data takes 2-5 times longer than expected.I havent done the maths, but 460GB seems a bit too low for 512!?If size is all you need, go ahead, but if you need speed, look elsewhere!
I needed a big microsd card, preferably a fast one at affordable price. It is big OK, its sort of affordable at just under $100, but it certainly isnt fast! I didnt have a chance to test it directly, but when in its supplied adapter, it tops at about 20-22 MB/s in benchmark tests (both read and write). Real life write performance drops under 15.Now, my computer isnt brand new nor lightning fast, so part of the blame may fall on it, but I have (4-5 years old) 16GB Sandisk that does 45 from the same slot! 3x as fast!Not very happy, but I can live with it...
Got on sale so price was right. As other have pointed out useable space on card as formatted (exFAT) & virgin/unused is reported by Win10 as 460 GB (494,860,763,136 bytes) - rather less than the advertised 512 GB even allowing for the 1000 vs 1024 arguments regarding proper definition of bytes/megabytes/gigabytes! Presumably the discrepancy may be accounted for as spare blocks or garbage collection space? Performance is not bad in modern system with reads averaging over, 85 MBs and writes just over 70 MBs. Large file copies do show regular, brief drops to approx 18 GBs somewhere around the 1 GB mark(s) but these may not be an issue during normal use. Overall, if the product proves reliable Ill be happy with it! One star off only for the reduced capacity.
I’m using it in a Microsoft Surface Go. As additional space. Works fairly quickly, is reliable and was a great purchase. I bought 2.Make sure your device works with this 512. Many cameras won’t accept it. I tried it in a DJI Osmo Pocket, and it wasn’t recognized.
