I absolutely loved the product. The instructions were relatively clear, the machine itself extremely customizable, and the clock relatively reliable. But the product only lasted for 3 months before it stopped working. There had been signs beforehand, like the number of servings per day changing randomly. However, after only three months, the feeder stopped dispensing food at its programmed time. It still dispensed food about half the time when the right button was pressed but did nothing during timed meals. It's a great product in theory but doesn't last long enough and isn't reliable enough to be worth the price.
