I had it on my slr, it only displayed 25 out of the 220 photos, it wrote each photo on the 25th photo while I can't format it.

Guys, unfortunately the memory doesn't work properly. I had it on a ZTE A310 mobile phone, then on an Alcatel Pop C1 and on a Huawei Y5, and now it's broken. Unfortunately, it was running so slow and it was slowing down the whole phone to the point where I thought there was an issue with my phone. It also kept freezing a lot and lagging. It took about 10 minutes to install a 25mb application. It's better to go with another company, it's really not worth it. Also, it was showing incorrect internal memory of the phone, for example, even though it had 200mb left, it was showing only 50mb. I replaced it with a Sandisk and now I realize that I have a quad-core processor in my phone and it has become incredibly fast
