I love the size of the device.  It worked great until a few months ago.  First, the shift key on the right side stopped working.  Then, the next day, the Enter key failed to work.  Since it’s too late to return it, I figured out a work around.  Then last month the Shift key on the left side fails to work to capitalize letters. I have to use the CAP lock key.  This weekend, in certain apps the typing feature randomly works or not at all. I have done troubleshooting.  Performed updates, etc.  nothing resolves these issues.  Great purchase price, but if it’s too good to seem true, it isn’t.
