RAC Paws by RentACoop DIY Auto-Fill Metal Cup Waterer Kit 2-Pack - Great for Small Animals, Pets, Bunnies, Ferret, Chickens, Hamsters, Guinea Pigs, Rabbits, Chinchillas, Mice, Rats

I was super excited to buy these for 16 rabbits and create a whole gravity fed water system. They worked great for a while. Until the plastic clips that attach the bowl to the cage start bending when rabbits but their weight on the bowl. slowly the plastic clips and support have bent so much the bowl won't stay clipped on my cage for longer than a minute. the little red screw does not help. in the pics if you notice how the plastic around the screw has bent. If i don't have the screw the bowl pops off, if i have the screw the bowl bends. it's a lose-lose situation. little bunnies might not cause these problems... i have new zealands.
Also, the one design flaw besides the material flaw mentioned above is the fact that if a rabbit lies under the bowl the bowl will be tipped up and all the water runs out.
Although the only times water wouldn't come out it was just because the bowl got a little too dirty. My springs have stayed in great shape for 3 months. My rabbits have not chewed through the plastic only the little rubber washers.
So im bummed about the plastic bending i really have no idea how to solve that problem. Ill try putting blocks under my bowls and we'll see how it turns out.

Love the idea and set up would work great if some weren't defective! Two or of the six leak water because the bowls overflow! (See wet spots in images) And I agree with another reviewer about eliminating the plastic for the parts that are located inside the rabbit cages & the hanging brackets!
Wish the seller would send me 2 replacements for the 2 that are defective! I really don't want to return all for a new set and possibly have the same issue.

Perfect tubing for rabbit watering system. Black tubing is preferred over clear or light colored due to blocking the light/UV which inhibits algae growth. The automated system has saved me SO much time and kept my rabbits hydrated much better than bottles that are always dripping and don't hold enough water. Rabbits will also drink more water from a 'bowl' system than from the nipples or balls in water bottles. Paring this tubing with a few other pieces ordered from Amazon has made an amazing system for keeping my rabbits in water. The water bottles were a terrible option. I think I'd even use this system for one or two cages, even inside/pet rabbits. When choosing the cups to use in the cages *GET THE METAL ONES*. Rabbits chew too much! ;-) I used these items to complete the system: "Rabbit Watering System Bucket Connector Kit to ID 5/16" Hose Include Bulkhead Fitting, Barb Ball Valve and Mesh Washer", "RentACoop® DIY Small Animal Watering Metal Cups KIT for Small Animals/Pet/Bunny/Ferret/Chicken/Hamster/Guinea Pig/Rabbit/Chinchilla/Mouse/Rat (6 Pack)", and Nigo Industrial Co. 3-Way Tee Brass Hose Fitting, 5/16" x 5/16" x 5/16" ID Hose Barb Pipe Fitting (Pack of 5)" (get the brass hose fittings instead of the plastic, more expensive up front, but it'll be the last time you have to buy them-don't get plastic).

I built 2 gravity fed water systems and after much research purchased these cups. Relatively easy to install, although I used pvc pipe, which made the drilling more challenging. I had plastic spirals that I had to remove with a file. With the pvc pipe being thicker than a bucket typically is, the plastic wing nuts didn't catch quite right; I put them on one system but not the other. I screwed the cups in tight enough to warp the rubber washers just slightly but upon filling the pipe, there were no leaks and water flowed into the cups as to be expected.
They also appear to be quite sturdy, as I knocked one off with lawnmower and it did not get damaged and reattached quite easily.
There was a bit of a learning curve for the 8 week old pullets; took me moving a water bowl closer and closer to the watering system for 5 days before they figured it out.
My grown hen won't use it period.
All in all a great product. The screws could be a bit longer to accommodate thicker plastic and the wing nuts could be better made. Would be nice to see it all in stainless steel as well.
A solid 4 stars!

I LOVE these so much, I bought ANOTEHR set of 6! I use these in my rabbitry in the summer months to make sure the bunnies have a constant supply of water!

Good stuff

I love these little cups. They were very easy to install in 5 gallon buckets. I use to keep fresh water out for birds and squirrels when I go on vacation and bird bath gets dry.

Great for our meat rabbits. These are easy to use with a 5 gallon bucket. Easy for my rabbits to drink out of. We purchased another set to have 2 water stations.

We installed these in our rabbit hutches. They were really easy to set up. Once we got the correct size tubing to attach to them they work great. No leaks. Really durable.

I LOVE these cups. I use them with my rabbits automatic water system. They can’t chew up metal! I do with they offered one that would hook to water directly behind the cup but all in all they seem durable and do their job well!

Do not like the space between bucket and bracket ! Wanted them with cage clips but not stainless bowls. Also the removable cups are very hard to remove without being heavy handed. Arthritic hands would have a hard time removing.

I bought these thinking that they would be a lot better than the plastic waterers. They are very strong and do not drip. There is always water available in the cup. I recommend these over all other waterers!

These leaked after installing them as instructed in the manual onto a plastic barrel. The nuts also do not thread tightly. Junk.

Made a waterer. Cups worked great

only installed one so far, but it felt very nice and no leaking so far. My bunnies adopted it right away

I’ve had alot better luck with these ones compared to the individual ones they sale with its own containers.

Highly recommend over the individual ones!

Love them for my chickens, ducks ,and rabbits!

They work really well and happy with my purchase. If I had any cons with the product it would be I wish the hanging ears where made of metal instead of plastic but none have broke as of yet.

Looks to be easy to set up.

Have chicken waterer cups for our quail, and tank waterer for small chicken pen. No water waste - Great! Now trying the metal cups for our Rabbit Grow Out Pen! Super quality!

Great product! Great family owned business! Great support.

I had the plastic version and they work good bit the girls would spill them if they bumped them. These metal cups dont spill! Im so happy with them! Rent-a-coop is a top notch company. Everything from the instructions to the product are high quality. They dont cut corners! Thank you for this! Id buy these again a million times over!

These work fantastic! Great concept, easy to install and easy to clean if needed. However, i’m only giving 3 stars because while the metal cup is great for rabbits and such to prevent them from chewing (i’m using for rabbits), the rest of the unit is plastic and the support clips on the back break off super easily and the rabbits chew and break the plastic parts. If the whole unit was metal, this would be a 10 star review. If you are using for poultry these would be just fine, i have these same cups but plastic cups for my chickens and they work amazingly.

I was skeptical about whether these would leak or not but they work excellent. I used them for rabbits, chickens and quail. I had a hard time with the plastic ones where they puch on the paddle because 1) the rabbits chew on the plastice 2) it's hard to tell if they are drinking out of them. With these you can see they have water in them and there is not learning curve for the animal to use them. I recommend highly.
