Review on 🐹 9-Inch Silent Runner Wheel with Cage Attachment for Hamsters, Gerbils, and Mice by Cecilia Love

After 5 minutes of running-in, the wing nut is unscrewed. For $30 it should be perfect, but it isn't. They didn't even move the plastic all the way. Here's an idea. Replace the wing nut with a lock nut and the seat cushion problem is solved. The lock nut is 5/16. I put two 5/16 flat washers between the lock nut and the other side of the medal stand, which completely eliminated rocking during movement. Now it never falls off. Just don't tighten it all the way or the wheel won't turn. I would give 5 stars if I didn't have to fix so many parts. Even my floor panel was crooked.
