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.

Changes directions smoothly. Unlocking them can take a lot of force. I usually whack the lever with a mallet and that does the trick. They are economical compared to other 3-inch casters.
