i have 1..it's xmas present for my furkid ^^
it's helpful enough to set 4 meal time a day for her so that we do not need to rush back home to feed her while we were in the midst of shopping ^^ and it's good to let her has her meals more frequent in smaller portion for easy digestion while we are away in the daytime for work.

i got mine from SummerPet, PJ..cost me around RM200++..it's for long term use, thus personally i think it's worth it.

saw ppl selling in lowyat too..but not sure it's new or used..
