Bests & Worsts Reviews from Amazon

I bought these for attaching to a 412 guitar cabinet. They were relatively easy to attach. They held up while being stationary and moving a couple times in regular load in/load out situations. At that point, the stem the wheel is attached to bends enough for bearings to start falling out, or simply snaps off. This is actually my second set of them as I'd hoped the Amazon ratings would overall be right, but I've now had 3 out of 8 of these fail, and the other ones are en route as they have a lot or give. Don't waste your money on this. If you're going to get something that breaks, go to your local hardware store so you can have new castors readily available or can potentially get a refund for them not standing up to any abuse.
