Decent
Color: Dark Brown, Size: 15.7", Color: Dark Brown, Size: 15.7"
Instructions aren’t very clear. Takes a bit to figure out. Pretty cheap quality, but seems to be sturdy. The metal basket part of ours came rather bent and had to do some bending to get it to fit right. Decent size could be little thicker. They look good though once up.

Works well
Size: 6.5 FT, Color: Black
This thing was a life saver. It has plenty of plug ports for the price and it's not huge. The footprint is a bit bigger than some others but it's not bulky. Seems well built and the fact that I can power all my electronics and still have the USB ports to charge my phone and things is nice.
