Easy to move the pallet around and lock in place. I like that when you lock the wheel, the pivot also locks. It moves smoothly and easily as needed on my patio.

Wheels fit better, lock and have no noise when the sub's are playing. Tires are quiet rolling and compliant but will flat spot a little after sitting in one position. No problem going over carpet and onto wood floors.

But the swivel may as well not exist.

The cabinet is about 6 feet tall so wanted smaller wheels for it. Have purchased several sets and have had no issues with any of them. Having large fastening screws and washers were a plus.

They work great on smooth surfaces and not so much on gravel. They have smooth operation with good bearings and good mounting plates. Great rollers, easy to install, comes with everything you need.
