Purchased this nightstand for a guest room.  Love the concept of USB ports available for phones and ipads, etc. It was pretty easy to put together.  I was slow and methodical, as I wanted to be sure I understood each step before I started it. Probably took me half an hour.  Attaching the knob was the slowest part, as I had to find a good phillips screwdriver to give me enough leverage to turn the screw.  Anyway, I've installed it where I want it and tested the ports. I came with a charging cable with three different USB adapters. I was able to check two (iPhone and Kindle) and they work well.
