Built a rolling general woodworking table and these casters work perfectly. Easy to screw in without the wheel getting in the way, the wheels are heavy duty and can take all the weight I've put on the table so far (>350lbs) while still rolling around the garage with ease. They also roll over or push little pieces of gravel without stopping or hanging on the floor which I was a bit worried about. The polyurethane is soft enough to have a bit of give to roll over stuff while still sturdy and strong enough to handle a smooth movement.
I did notice the stops on the wheels sometimes engage at an angle, left or right instead of straight down, when I use my foot so I have to disengage and reengage them to ensure a solid lock. However, while locked they aren't going anywhere. If anyone finds that as a negative I didn't remove a star because the lock and release are so simple and with ease you can use your hands without worry of a pinch-point - this was key for me since I have all 4 wheels on my table these swivel casters and sometimes the direction of the wheel is under the table so I'll need to use my hand to release the break instead of my foot.
I say these are the best wheels with my research I could have purchased at this price-point for my use-case and would say they are worth the few extra dollars compared to similar models at Harbor Freight, Home Depot, Lowes, or even on Amazon. This was my first Grizzly purchase, but I can now say for my growing shop it won't be my last!
