Works just fine. It's big and heavy, but I'm using it to grind and smooth welds on an old motorcycle frame so I'm trying to get into some really tight spots. The spring was a bit loose when it arrived so I took it out and opened it up a bit in the vise. Tension seems good now. It comes tie wrapped closed so the spring may have taken a set being under tension for so long. I might retrofit the head to a better quality grinder body if this one fails. Anyway, seems worth the money so far.
