Tiaki Automatic Feeder
Positive:
The product is very practical for the low price.
There's an audible signal when the new food chamber opens.
Programming is really easy.
The chambers are dishwasher safe.
Negative:
The green lid can only be removed by basically yanking it out to clean the trays, and over time the holders tend to break.
Unfortunately, there are no extra trays or lids available as spare parts, which would make the feeder last longer, since the bottom part with the timer never breaks.
