Already 2 have gone bad. The tape broke on one reel and on the other. Good for a homeowning job, but if you're in sales, go for Milwaukee or something else that's been tested. Spend once, not twice. It's great that you can always return it, but that's just stupid. I like things that work. But if it's a homeowner's project, it will do the trick.
