Used a 128gb model of this in my phone for the past year, bought a 64gb to go in my phone and moved the 128gb to my Nintendo Switch. Fantastic read/write speeds for the price. Switch games load quickly and no wait times when taking RAW pictures and recording 4k on my phone.
My only gripe is the USB reader. It's very small, durable, good build quality, and great read/write speeds. However, getting the microSD out of the reader is a bit of a pain. Once fully inserted barely any of the microSD sticks out so it's a bit difficult to remove.
Other than that, caught the 64gb microSD and reader on sale for $29 so it's a great deal.
