Because of the reviews on here I make it very dry food only round without edges to buy (no asterisk or hearts) and voila, so far I have not had a single block in the system. The automatic feeder works very reliably.
A small drawback is that slipping of the lining when the container is almost empty: there are only a few portions of the reservoir, so you have to push the food with hands in the middle, otherwise remains the feed are on the edge and the portions are getting smaller ,
One point deduction do I make the non-removable battery. With us, the automatic feeder is in the kitchen and I would rather connect it via a power cable, as always on the battery indicator (which is unfortunately on the back of the automaton) to worry about.
The earlier criticized noise I do not feel too bad as. The device is not super quiet, but somewhere the rotational movement of the blade must come indeed. Since the automatic feeder starts only when feeding and causes noise I find this criticism negligible.
Conclusion: Recommended for people who want to schedule one or two extra meals for their Mietzen, even if one is gone shopping. Nice side effect is always the same feeding time after which the animals are sent quickly. Should give a little one night when choosing a dry food, then there are no complications. Outdoor operation has not been tested.
