Review on Swivel Wheel Combo Caster with High-Quality Screws - Material Handling Products by Jesse Wells

I ordered blue because the picture showed wheels that looked like they were making good contact with the ground. Unfortunately, they were rounded at the bottom, not flat (like the picture, they're red, just blue). Not a big deal, still great value for money. It feels like they have a bit of play, although the table still wobbles a bit even when not being pushed. Not the best choice for my new workbench.
