Amplim 64GB Micro SD Card, 2 Pack MicroSD Memory Plus Adapter, MicroSDXC U3 Class 10 V30 UHS-I Extreme High Speed Switch, Go Pro Hero, Surface, Phone Galaxy, Camera Security Cam, Tablet, PC

I'm a photographer and, though my camera takes SD cards, I like to use Micro SD in an adapter. then I can use the cards for anything (camera, phone, tablet, etc). I tried this brand and size before and am totally pleased with the quality and speed for my work. I don't do video, but these are rated V30 which should be fine for anything. I tried this pack because I didn't really need so many adapters and it saved a little, at least when I got them. Besides, the price of cards has gotten pretty reasonable and - with my work - it doesn't hurt to keep a couple of spares in the bag.Recommended!!!

Works great

The card appears to work great in my GoPro and then I've used the holder to view the footage - all went without a snag. If I could make one suggestion it would be to have brightly colored case to hold the adapter so you can easily find it. Things like that can disappear quickly.

I just had to say this, not about the cards but about the packaging. This is the first time in my life that I've seen a "zip tab" thing pull out of the packaging like it was supposed to. Not only was there a long tab to pull and remove, but then you were supposed to pull the entire back of the packaging down and it was supposed to zip right open. And IT DID. I'm well into Medicare, and this is the first and only time in my life I've seen a package so well designed and was actually easy to open. Kudos to Amplim for taking such great care in their product.Oh, and the microSD cards worked great, too!

I bought the 2 x 64GB pack which I have received but other than the read/write test I have not used.The first picture is showing what I used to do the text. The card reader upper right is a USB 3 and is quite quick.I used a windows 10 PC with a i9 9900k with 2080ti, etc so computer is also quite quick.To the second picture I notice I have them in reverse order thus first test one on the right.Right most was taking one of the micro-SD cards and inserting direct into the Kingston card reader.Middle is taking that same micro-SD card inserting it in the adaptor (top left of first pic) and testing to see if the adaptor would have any MAJOR effect on results (It DID NOT).Left most is the other micro-SD card again directly into the Kingston card reader.Now a couple thoughts have used many SD and micro-SD card over the years (along with SSDs in computer).1. When looking for a micro-SD card for things like Dash Cam or home security cams I think it is a good idea to look for a V30 on the card.2. I have seen (and it could happen with this card only time will tell) that the "lesser known" brands over time may see a CONSIDERABLE "fall off" in performance. So out of the box they work great, but months down the road they may be nearly "dead in the water".So in conclusion, out of the box these cards look great, but only time will tell if they continue to perform well.I think I'll put one in my dash cam and if I have a falloff in performance I'll be sure to let you know.

I am using this in my Moto G phone to expand internal memory. It is inexpensive and works as specified. If someone had told me 20 years ago that I would live to see a 128 gigabyte storage on an object somewhat small than a postage stamp, I would have said, "Humbug." Now all we need is a president whose staff can organize an Easter egg hunt.

I'm using this in my HP Spectre x2 as a second drive and so far read/write is pretty snappy. I haven't done a speed test yet, but for my uses, this works well.It came already formatted with no extra garbage on it which was good. Just plug it in and go.We'll see how long it holds up.

It works well but have noticed that it has issues. It doesn't always retain a picture and will create an error message where a picture was supposed to be. It does the job but should definitely have a picture backup account in the cloud to make sure that you don't lose out on prescious moments.
