I bought this product to try it out with my Samsung Galaxy S7 Edge. This will work with S7 as well as it should. If you have any other phone beside the two that is mention. Ask sale rep, friend, etc if you phone support 200gb. Some phone has a limit to it. It will only support an addictional 32gb, 64gb, or 128gb. Ask first before buying just to be sure. My phone only come in a 32gb and it was market to support up to 200gb. My phone might even can support 256gb with samsung new micro sd card. I will give that a try later down the line as it cost $250 without tax or when I have the move to do so. I'm really happy with this product it work really well with my phone and I haven't had an issue with it. For the price that it is at $80 without tax. In my opinion a really great price since it was label as $250 without tax. It also come with an adapter which is really nice. The adapter is for you if you want to transfer any file, picture, or anything else between your computer or camera. If you are thinking about getting a micro sd card at 200gb. Well here it is at $80 without tax and with adapter. It might even cost less later down the line, but I don't know, so it is up to you to get it now or not. In my opinion I think this is a really great price. If you are going to use this card for a cellphone. There are information out there on how to move picture, file etc to the micro sd card. Also some apps but not all can be move to sd card. Any system app are the one that you can't move to the micro sd card without rooting/jail breaking your phone. Extra information for you. The package label 200gb but with formatting and how it will adapt to your phone, camera , computer etc you might not get exactly 200gb. It is just extra information for you to know. I still love the sd card and I do not regret getting it. If you are planning to buy it I hope you enjoy it and have no regret buying it. If you already bought it go crazy with it. Take ton of picture, video recording, file transfere because you have 200gb give or take no need to worry about running out of memory for the average user. Hope this review help some of you guys out there and have a nice day.
