I've bought a lot of stuff there over the years, mostly recently some air beds that performed well on our annual camping holiday. I'd bet the o-rings are fine.
Got some good (road) motorbike boots too.
Tools? I've had mixed fortunes on that front. Some drill bits I got were completely unusable, and a set of wood chisels were almost as bad. I did get some scrapers that are really good though.
