With the crazy hours I work I never had a feeding schedule for My cat, so I would feed him more then he needed in case of coming home late, therefore his weight got to more then it should, so when I saw the Healthy Pet Simply Feed I had to try it. Works as advertised and now he's getting back to healthier weight. The washable parts easily remove for cleaning and canister holds good amount of food for when I go out of town for several days. Only thing is wish it came with optional power cord as it was extra cost to buy separately as I worried battery would wear out when not home. I like how you can set amount of food but be careful cause I think measurements are not accurate and feed more then says. Overall worth the price for convenience.
