I'm currently using the food one but the water one the dogs got dirty and the bowl needed washing when the water tank was still half full. Water is good if you're going to be gone but not for everyday use when you have several dogs like mine.

Pros: food works well

Cons: water bowl area gets dirty so still have to wash it often

I love the convenience of the feeder. I was concerned my dog would overeat, but she really doesn't. She has remained a healthy weight for her size... and I have been using the feeder for years. I ended up throwing the water cooler away a long time ago. If you don't wash it every couple of days, mold will grow in it and that can't be good for your pet.

Pros: Feeder is extremely convenient

Cons: Water cooler doesn't stay clean for long

this has a lot of benefits other then the free feeding

Pros: great for the water with multiple dogs

Cons: would not use for feeding

these are so great. i use them for my cat. the dog is afraid of the noise the waterer makes.

Pros: easy

Cons: none

My mom got these for the cats and dogs. They are easy to use and we don't have to fill water everyday. The food is filled everyday. They are easy to clean too.

Pros: Don't have to fill food and water everyday

Cons: Heavy
