This feeder does exactly what it's suppose to do! It allows one of my cats to always have access to her food without her brother constantly eating everything. Occasionally, as the male cat sits near the PortionPro RX, the door will briefly & part way (~25%) open. I discovered this is a built in safety feature to prevent an unapproved animals tag from getting trapped by the door. This is a neat feature that hadn’t even occurred to me to be a potential problem. Overall, I'm very happy with this feeder & fully recommend it to others!
We purchased two of these for our two dogs. I have been extremely impressed with the accuracy of the portions as well as the closure of the bowl from the wrong dog coming near. We have it in open mode and it closes when the other dog comes around. It's working great!
My skinny cat who prefers to free feed can finally eat normally, while the fat one is beginning to lose weight!
I bought 2 these for my 3 cats & set them for 6 meals/day at the same times. 2 cats eat the same amount so I assigned them to 1 feeder & the other cat to his own. I was concerned this wouldn't work very well but now that it has been a month, it seems to be working well. It took about 1 week for them to get used to them. The first time they hissed & ran from it when the door opened now they run to it when they hear food dispensed. I would've bought 3 but they are pricey. I bought these because they are the only ones on the market that holds a lot of food & can divide the daily meal into 2-6 feedings. I am very happy with how they are working. Sometimes once an unassigned cat goes to the wrong feeder, it will take a little longer than I think it should to open again for the assigned cat. The only things that would make this feeder better would be a battery backup for loss of power & tags that wouldn't need replaced every year. I am concerned the tags will stop working when we are gone so would be nice it there was an indicator when they are getting low. Other than that, I am very happy so far with the feeders & may at some time order a third.
I have three cats that eat different food and are different sizes. These machines are great. It did not take long to train the cats to use them and they all know which one is theirs. However, I do wish they were a little quieter.
