Well made and easy to fit. So far it's worked well. I had to tension down rather than the preferred up - a litte bit more sensitive to chain tension as a result (chain needs to be tighter) but the DMR is coping well.
Having struggled with other less expensive chain tensioners this one seems to do the job perfectly and is very adjustable. I guess you pay for what you get!
