I'm running two of them. I have two LV under the workbench to replace them with but, they are still doing the job so I guess I'll wait till one dies. I had to open about 6 of them to find 2 that were workable. I then basically dismantled them in the shop and cleaned up a lot of the poor fit and finish. Took all of about an hour for both and they have been used almost daily since May of 2007 without issue. I'd say I got my money's worth.
