512GB Micro SD Card, Amplim Extreme High Speed MicroSD Memory Plus Adapter, MicroSDXC SDXC U3 Class 10 V30 UHS-I TF Switch, Phone Galaxy, Camera Security Cam, Tablet

The Amplim Extreme Speed 667X 100MB/s UHS-1 256 GB MicroSDXC TF Card once installed worked perfectly in my Samsung Galaxy A 10 E smartphone. After seeing it and putting it into my phone's card tray and then reviewing all the phones etc. that it was advertised as compatible with, I drew the conclusion that it was a "universal" fit. It didn't snap into the SD slot of the phone's card tray. I had to fit it in and then press down a little so that it stayed in position. Once I did this it stayed securely in the try and I could return the tray back into the phone. Once into the phone it behaved beautifully. I'm already storing videos on it. Good Luck to all buyers, Frank

Bought a few other sd cards before hand from other makers before I came across this gem. The other ones have not held up, became corrupted, or had issues of xfering data to them. This little gem however does not have that issue and is all I buy now. The price is pretty great, and takes forever to fill up the storage. I own three of them now, one for my tablet, one for my phone, and another for misc when I need to xfer crap from one laptop to another (if my passport isn't available).

Card works great in the new (2/18) Mavic Air drone, where the others don't The Air needs to be able to record at 100 mps. My only complaint was the packaging. This very small card was sent in a much too large box when it would have easily fit into an envelope. But, the box is big enough to be repurposed, so maybe it's not that bad. Have not had a chance to use it all that much due to poor flying weather in Dallas the last week. The card will get a good workout when it all clears, and will report back on any issues down the line. For the price, wish I had bought several of them- but wanted to test just the one at first, just to make sure it worked with the Mavic Air.I forgot to submit this, and it is now March of 2018. Have filled the card and reformatted a couple of times. All is working so well, I bought two more of them for two other drones. My only suggestion would be to have a distinctive marking on the cards to identify them from all the others. The ones I received are black with some gray writing on them. How about a large dot? Even better for me at least would be to have different color dots for different sizes- Red 64K, Blue 32K, etc. Maybe start an industry standard. Right now, all sizes look the same and hard to tell a 16K from a 128K without reading glasses.

Initially, I was little nervous about what the best company is providing great memory cards. I found myself stuck with this brand actually the price is reasonable as well as it’s reliable. I’d definitely buy it again.

Gracias me encanto ahora ya tendre mas espacio para las fotos familiares😊

As one can see in these photographs, I had an unwelcome guest or two in my yard for a few nights. Could not figure out where this cow was coming from until I set you my infrared game camera. And several neighbors have had their cats go missing; including one of mine. Now I know it us coyotes coming into our yards and snacking after midnight on our pets. This SD card caught clear photos of the beasties.

Never heard of this brand before, but decided to take a chance with it. When I got them in I did speed test with them the 512gb card got 66 write and 87 read which is great. I also got the 256gb card and that one got 68w/89r. I also fill them with video files of mine to test space and the files were readable. I did not check though every single file, but enough to be satisfied that they were correct. If the card work well with some of my other devices will get this brand again. I did try the cards in my HiRes audio player and had no problems with the cards. They were fast both with my iMac and Windows computers.

This Card is perfect. I opened the package, Installed it in my Laptop computer running windows 8. Reformatted it without the Window's Quick Format option Checked. Which is performs a Byte by Byte format processes and it took 8 hours to complete. but it passed with flying colors. Great JOB. I have purchase a lot of cards before and the first clue is when windows report a 256 GB card has 256 GB available. THEY Fail every time. But the Amplim Card reported 240 GB and I was relieved. I have actually Found a WINNER. I am going to enjoy this card. Thanks a Lot
