Pros: Cost efficient, decent quality of build, light weight. Cons: the rubber knee pads are somewhat uncomfortable, I ended up taking them out and wearing my own pads. I used these every day professionally when I was working with a high rise construction pan deck flooring company. These are not gonna be like 300$ ones so it's not fair to compare them, but if you're building a garage and wanna slide your floors, these aren't a bad option.
