I knew this took AAA batteries that weren't supplied, but also thought it had its own internal battery, hence the USB charging port. It does not.
Every time you turn it on, the volume resets to 12 of 15 levels. Volume level 1 is SO incredibly loud. Lowering the volume is a pain in the butt as the button gaps and the overlay don't quite line up perfectly so you have to press under the button on the graphic to do anything.
The keyboard doesn't want to stay rolled up, if you're going to buy this you're hopefully only doing so as it can roll away, but also invest in a good velcro strap.
Honestly, I'd return this if I hadn't accidentally thrown the box away already.
