Overall we love the bin, eventually!  The first one came looking like the warehouse staff had played football with it was so unbelievably dented, all over.  Some of the reviews had said the same but we chose to take the risk.....  All said the Wayfair staff was awesome at sorting it out and we had a replacement sent out.  It took a while but got here undamaged and we love it.  Require 4 AA batteries not included.  Can activate when walking past it - infa red sensor.
