Pros: Honestly, this is the best peice of fish equipment i own (and that is saying something!). It's easy to figure out the digitable timer--there's a step by step guide for it. I love the number of feeding options.

Cons: no cons.

Bottomline: Excellent product. Simple, reliable. It will do everything you except from it and do it well. Seller very responsive to issues - great to deal with - prompt service and outstanding communications. Highly recommend product and seller.
