Great for hamsters. Just make sure you get the right size (medium 7.5") for campbells, winter whites, and robos. The large (12") for syrians and Chinese. Not my first choice if you have a syrian or chinese due to how much cage space it takes up but if you have a shorter cage it will work unlike a traditional wheel that might not fit.

I have the medium for my hamsters but I bought a large for my hedgehog. While it works for hedgehogs I dont recommend it for them. There have been problems with it breaking under a hedgehog's weight (I didnt experience this the 3 or 4 months I had it but others have). Also, Hedeghogs pee and poo while running. The poo will stick to the grooves of this wheel and that makes it hard to clean.

My long-haired Syrian hamster, Russell, LOVES these horizontal wheels, but I find the largest size disappointing. We are on our third, properly used and cared for 12" flying saucer wheel in as many months, and I think it will, sadly, need to be our last.

The first wheel we had was the smallest option - which I purchased since it was what Russ was using when I adopted him - which remained in tact. He outgrew this so we went to the next size up, same story. But when we ordered this largest size, the first cracked in shipping (not the fault of the manufacturer but inconvenient) and the second was noticeably warped when it arrived and snapped suddenly during routine cleaning after two months.

If you are looking at the small or medium sizes, I would give them *high* praise and five stars! They're basically silent, sturdy, easy to maneuver during daily spot cleaning, offer a nice extra hideaway (Russ loves to nest behind his, especially the medium sized wheel, which he doesn't do with his vertical wheel), completely safe for tiny toes, and I couldn't be happier with them. But the largest size is noisy, easily broken, more difficult to clean, and too expensive for how short it lasts.

I decided to go ahead and buy one last wheel while I try to find a good alternative since I know he will use it and enjoy it. Similarly, I'm giving it three stars, because it truly is Russell's very favorite running wheel. And, when it works, I would give it a five. However, I can't recommend it based on how short they last.

This wheel is completely silent. I use it for my Syrian Hamster and she LOVES it. My hamster has a problem with always storing food in her wheel and running in it (silly hamster!) but this fixed the problem. Random color (I got green) wish I could have picked the color, but no big deal.

It broke from the base within a couple of months. My hedgehog is small for his age, and still a baby really. So there's no reason this wheel should not have supported his weight. He became depressed after it broke. He hasn't been the same since, and that makes me angry at Ware Manufacturing for selling such a weak product.

I didn't want to buy another one of these for obvious reasons - that it broke quickly for no reason except maybe bad design and because I'm not that rich. So, I've tried to repair it to no avail. I tried driving a screw through the center like another reviewer had mentioned but I was unable to replicate their success unfortunately. I tried other things. Eventually, I bought him a round wheel, but he doesn't like it. He enjoyed his flying saucer wheel and hasn't been the same since it broke. I could either buy a new one every month to keep him happy, keep trying and trying to repair the old one, or beg him to please give the other wheel types a try. I'll keep trying to fix this wheel. He loved it. but it shouldn't have broken after such a short time. In its design, there's not enough support in the base. It's clear when looking at it now that it's snapped off, and by considering that the weight put on it while your animal is running on it is concentrated at the bottom half of the wheel at all times. A reinforcement in the base would offset that issue and prevent breakage, in my opinion. That's what I will continue to do or I will use the parts to build an improved version with a reinforced base. The spinning center where I need to drive the screw through has posed a problem for me. Suprisingly, since engineering is a specialty of mine - however, power tools are not. Any advice on how I could achieve this would be greatly appreciated if a reviewer has found a sustainable solution to the structural problem in the base without affecting the spin. I've so far only been able to reinforce it enough to keep it together but it results in too much resistance. And so, an awkward spin that is not smooth due to the increased resistance he isn't strong enough to get a spin going. I want my hedgehog to be happy again and I want Ware Manufacturing to fix this defect with a simple reinforcement before selling more.

I bought this for my hedgehog and put it in her cage before going to bed. When I woke up in the morning the wheel had snapped off the base. My poor baby didn't even get a single use out of it before it broke. If you're looking for a wheel for a hedgehog or similar small pet I recommend the Carolina Storm Bucket wheel. Its about twenty dollars and super durable and well built, the bearing is designed to bear weight, the base won't tip over, plus a wider wheel to make your pet more comfortable. I'm sure the flying saucer is great for pets who don't weigh too much to break the bearing but if you have a hedgehog look elsewhere.
