Well I like engineering. PetSafe seems to to do the best job and always provides a replacement part for their products. I bought this for portion control for my cat. So far so good. I also have the Platnium Drinkwell Fountain and PetSafe Scoop Free litter box. Everything has held up extremely well and I'm hoping for the same from the feeder. The design seemed better than most almost like a Keurig and everything clicks together nicely. I love the fact that the unit can be disassembled for a very sterile cleaning. Good job, PetSafe! Have had the Drinkwell too long with no feeder while others were on the market. It took you along time but I think you came in with the superior product.
