nice LITTLE tables
Color: Black, Item Package Quantity: 2, Color: Black, Item Package Quantity: 2
these tables are ..... easy to assemble sturdy nice to look at HOWEVER missing 2 stars for... they are small and plugging in items such as my laptop cord made it bulky and always in my way. if there was a middle shelf that would help with the small tops if the outlet bar was on the side or under the top that would help with the bulky cord issue

Need Battery's

Good floating shelves. I mounted the light strip on the top instead of the bottom because they don't stick well. For the price I wish they came with a set of batteries for the pack and the remote. But over all sturdy and well made.
