Pros: Have a large reservatory, than you can leave your fishs alone for serveral days (the exact numbers of the days will depend of the numbers of feeds per day). This gadget use a "AA" type battery, who comes with the product. You have two way to fix the gadget in aquarium.

Cons: Sometimes the flakes (fish food) drop over the support fixed in the aquarium instead of the water, but its a minor problem. The "timmer" its a little big, then you have to find a place to hide it. The price its a little expensive.

Other: Buy it if you need an automatic feed for your fishs.
