Review on Mobile Roller Locking Wheels for Daily Life by Brittany Lawrence

Excellent rolling mechanism. Supports very heavy items. Used for washing machine. The car moves easily and I like that the wheels lock when requested. The only thing I don't like about this product is the 4 corner tabs. Nothing is holding them up except the weight of the washing machine. I have found that they move when trying to place the shim on the roller and when trying to adjust the shim on the roller. It would be nice if there was something to keep the four pads from slipping or shifting.
