Overall I have been very impressed with this product.  Well made, good size, easy to use.  Plenty of storage space for the food and a good sized bowl.  The cats have still not figured out how to access it.  Only two comments are:  1.  this unit does not come with a power adapter, it is battery operated.  I would have preferred to just leave it plugged in and will need to purchase the adapter.  2.  The programming was a little challenging to set up.  Not prohibitively, but I had to pay close attention to the directions and refer to them frequently while setting up.  That said, once set up, everything works as intended and I have not had to mess with it since.  Recommend. [This review was collected as part of a promotion.]
