It is hard to find a side table with a finished back and drawers.  The slide out extension and power outlet (with a USB port) were an added bonus.  I bought two and they are perfect with lots of storage.  It would have been nice to have some color/wood options, but since my furniture is eclectic these fit in nicely.  
The outlet isn't deep, but there are so many different adapters available it hasn't been an issue. 
For the price the finish could have been better, there are a few minor imperfections, but nothing I can't live with, and I'm sure no one will ever notice.  The drawer sliding glides aren't the best quality, but they work.
Overall I am extremely happy with the tables and the Wayfair customer service.
