I bought & installed it for my dad who’s 83 years old.  The controls and remote are straightforward and easy to use.  I had a few issues with installation, though.  The supplied foam strips that are supposed to tip the A/C back slightly (to drain condensation) didn’t tip it enough.  I was able to use some of the excess white foam blocks to get it tilted properly.  The other issue was the frame that surrounds the unit to cover the gap.  It was too small to fit properly and I had to leave the bottom of the frame open.
