Yeah but the expensive ones can cost $800 - $1,000 pretty easily. The HF ones are what, $140?
I think this is just a matter of expectations. I had no problems using the HF dollies to roll my cars around my shop even by myself. If I had a professional shop and a bunch of cars I had to move all the time then I wouldn't use HF dollies. But for a hobbyist with a car or two that has to rearrange their shop to do different work once and awhile they work fine.
It's like most HF stuff in my opinion. I wouldn't recommend a HF welder to someone that welds all day long for a living, that's not going to hold up. But if you need to weld in a couple of patch panels or a set of subframe connectors in your garage they work just fine and you don't have to spend 5x as much.
Entirely possible. They're just cheap casters, nothing fancy. And clearly quality control is somewhere HF saves money. But they also exchange stuff pretty easily if you get something that doesn't work right, so as long as your comfortable taking something back if it's not working right then I don't see it as a big issue. We all know why that stuff is cheap, sometimes its gonna mean you get stuff that doesn't work. And yeah, something that costs 5x as much should work better!
