I read tons of reviews. But didnt want to buy 3 devices. Found a 3 way splitter (mentioned in other reviews). saved my sanity and made us get this auto dispenser. I'm due with my first in July. I cant free feed my cats because they will get fat (they never used to bother us for food when we free fed them-sigh). They have lost a combined 4 lbs since we started scheduling thier foods & are no longer obese!! But this scheduling came with them bombarding us in the am. Cant have that with the baby coming!So I took a chance on an open box like new with slight scratches. I'm very pleased to say even the open boxed device works!I got it a day or 2 before my splitter and adapter, so I used that time to clean and air dry. Install took maybe 12 minutes? Make sure all items/components are tight, secure, & dry!The programming was prob the most difficult, but its so worth it for the benefits! Now it find it fairly easy! It would be nice if the screen had a blue back light or something so it's easier to see. Think grey screen with black letters; that's what this display is like. When programmed and ready, it shows the buttons are locked and the next time for feeding!I've heard some say they had issues.I did buy the adapter separately. I've since had 2 power outages and all I have to do is set the time and then set to custom (vs the preprogrammed cat or dog) and it remembers the feeding schedule without me having to reschedule the feedings! Very thankful for that lil feature since power outages are very common in the summer here!You will have to force feedings a couple times because the conveyor doesnt have food on it! At first I was like wth! But after doing a couple force feedings, it worked perfectly.TIP: dont use slow feed unless you have larger portions. Since you can schedule up to 12 feedings with 1/8c as your lowest, I just do multiple 1/4c feedings. The smaller amounts just take way too long to dispense on slow feed!We use blue buffalo cat kibbles and have no issues with jamming.It took about 2 months for my cats to correlate the feeder with feeding rather than us making it magically happen. They have now completely stopped tormenting me in the mornings for food!I give them wet food at night so it's just for morning breakfast and afternoon snack!I will say we have messes because I cant secure the bowls and the cats drag the bowls, but honestly the cats love the hunt... they go nuts.Make sure to read the cleaning recommendations! Def dont want to ruin your new life saver!My cats are brutes! They even tried to bite the lid off. They haven't been able to open it no matter how hard they try. I do see that some say it could be tipped over. Ours is on the floor. They would have to use some serious skill to knock it over with full food for sure. Since I have the splitter, my cats cant stick their paws up for treats.The only negative I have is that now my cats associate the sound to cereal pouring into a bowl, and they run in all excited and confused lmao
