I recently made the decision to get some pet mice, but as a first time mouse owner, I was very curious about things to get them. For exercise wheels, I heard horror stories about other ones with slots that feet could get stuck, tails could get trapped, and general uncomfortable situations that I, as a first time owner, was unsure about. Enter the Ware Flying Saucer Exercise Wheel. It had good reviews generally, seemed like it would be quiet, and didn't have holes in it. The price is was fairly decent, so I took the leap and got it.What I found is that out of the three females, two of them love it! The third doesn't seem to really care, but I'm chalking it up to her personality as I guess she enjoys eating more then exercise. The other two have no problems running and have tested it at different speeds. One generally lightly jogs on it, probably training for distance running, and the other sprints on it, obviously training for the 100m Dash. The wheel itself spins great and is quiet to the point where it's a non issue, but you can tell your little friend is on it. Certainly not a bother at all. The color I received was purple, it does say colors may vary, so if that's an issue be aware. It wasn't for me.Cleaning is easy and I have yet to experience any sort of problems with it. All in all, for my first experience with a "safer" wheel I'm giving it max stars because it does exactly what it needed to do, is simple to clean, and obviously works like a charm.
