When my mat goes in the maker it just slides itself to make it work without any troubles. With the wheels, it moves easier and the vacuum can get under it. Now when i need the occasional tool, it rolls out without a fuss.

I put 4 wheels on it and as soon as i turned it over and the weight on wheels 2 wheels broke off.

These wheels are big, strong and extremely well made. Brakes hold securely in place. Worked great for a mobile work cart. Harbor freight cart.

They roll smooth, lock down tight and don't budge. They swivel and roll with absolute ease. I have to unlock them by hand, which isn't a big deal, but it would be nice to be able to do it with my foot.

The bolts, lock washers and nuts are sturdy. Definitely heavy duty and came with screws and screwdriver. They are so strong and sturdy.

Whatever bearing they used for the plate feels crunchy. Didn't hold up.
