These rollers are fine. They seem robust enough for my needs: moving around my desktop. The metal step is a bit flimsy and I am very careful when I have to lift the table not to bend it. IMPORTANT NOTE: I recommend buying your own screws as the ones that come with his product are of poor quality. I broke 5 during installation (see attached photos). I was able to pull out 3, the other 2 should have stayed at the foot of my workbench. The good thing is that it has 3 screw holes. If the middle one breaks, you can use the other 2 whole ones. But save time and hassle by using your own heavy-duty screws. You are very bad. Also, they work very well and do their job. UPDATE 3/7/2021 After more than a year of installation they work great and I would recommend them for the price. I am adding another star from 3 to 4. I'm deducting 1 star because of the cheap screws that come with the product. Go ahead and buy this product, it works very well!
