To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I brought this feeder because I have 2 cats. One is very skinny and needs access to food all the time. The other is fat and is on a diet, so he's always trying to steal food. I brought a slow feeder for the fat one, which I'm very happy with. And then I got the surefeed feeder for my skinny cat. After buying it, I realised I had to also buy the flap that covers the back of the machine. But that wasn't enough to deter my fat cat. So I had to also buy the HUB, so that surefeed costumer service could remotely set the feeder to "intruder mode". The app is quite limited in options, but the intruder mode worked! However, the amount of food my cat ate shown in the app was always completely wrong. I contacted costumer service again and they said probably the scale was faulty and sent me a replacement feeder. The second one, however, was even more buggy than the first one. It opened on it's own for no reason and sometimes ignored the intruder mode. Fat kitty had a great time! Probably there was something wrong with the chip sensor, so I complained again and they replaced it with a third one. Guess what? Intruder mode is once again not working properly and I already completely gave up on having the correct amount of food displayed in the app... In the end I ended up returning everything. It's a shame, because this product was the perfect solution to my problems, if only it worked properly... I know there's some people online who were luckier than me and still have their feeder working perfectly (at least when it comes to intruder mode) for a very long time. I should have kept the first one and just ignored the amount of food on the app. Costumer service was great. They just need to fix some problems in this product.
Overall I LOVE the concept of these devices. I wish similar products like these were available for large dogs. I am 50/50 with these bowls. For the most part they work well. My only concern is the accuracy. I bought 2 of these at one time. One bowl works fantastic. The other one is iffy with the accuracy. The one that works great only allows the assigned kitty to feed from it and keep withers out. I have 3 cats total and they're all on sure feed bowls 2 bowls are these models and 3rd is lower end model that can't be used with hub.
The bowl that is iffy. It will let the assigned kitty and 1 other feed from it but keep 3rd kitty out. After some confusion and frustration, I decided to attempt to reset and re-assign only one kitty to the bowl. Despite my attempts it still allows 2 cats to feed from it instead of one. I don't known if this bowl is a did or what because the others work great.
I am still hopeful and with a positive outlook since I have had more success than failures with these bowls. I still would like to keep trying and maybe acquire a replacement for the "dud" feeder. My goal is to have ALL 3 kitties on same model of bowl and connect bowls to hub sold separately to better monitor their feedings for health observations and prevent any potential medical issues.
