Silent Hamster Exercise Wheel - Ultra Quiet Spinner for Hamsters, Mice & Small Pets - 7 Inch Yellow Small Animal Running Wheel - Perfect for Nighttime Play & Cage Enrichment

great wheel but the water bottle is garbageToo small for my fat long haired Syrian. It also wobbles which bothers me. The water bottle stand is way too low for my Syrian as well, but the bottle itself seems fine thus far. I’d recommend for small mice or a dwarf hamThe water bottles are terrible. One continuously leaks and soaks the hamsters bedding and the other the hamster can not get any water to come out. I believe it’s the come seal or gasket that fails on them. I missed the return window or these would have been returned. Not worth the money. Useless and poor hamsters are dehydrated from them not working properly.My dwarf haster love it but the water bottle does not flow. I had to buy a different brand.Very quiet. It has a heavyweight base to stand alone or the option to attach to the cage. It works perfectly in both locations. The water bottle is wonderful too! I like that I can mount it on the cage or easily put it in the bottle base/food container. I’m very pleased and my fancy mice love it too! Thank you!Nice, sturdy, quiet and perfect for our robo hampsterThe heavy metal stand to the wheel makes a lot of noise if rattling against bottom or side of cage when my gerbils burrow around itAlso the actual wheel is too close to the metal stand that if any bedding gets underneath it it jams the wheel
