Pros:First, the price of this feeder is in limits for what I would pay for it, not so expensive like the other feeders from pet stores. I like the design, it's very simple, no complex mechanics inside. The food container is large enough to hold at least for 2-3 weeks of food for my turtle.
The tray dispenses also pellets if you set it to right position and amount it dispenses is roughly the same every time it works.
Also nice thing is that it came with working batteries!

Cons:The manual came, so setting this device was an experimental venture. Luckily,so you don't have to spend time figuring it out and worry if the pets are going to be fed while you are at work.
The motor is not strong, If you put too much food inside, it will struggle to rotate.

Bottomline:If you are not at home every day, then I would recommend to buy a feeder for your aquarium pets.
