Negative Positive
Title: UPDATE: Not so great!
Review: Works great, applies easily. The door now operates more quietly than before. I was skeptical that such a small tube was enough to lubricate the entire screw, but it was exactly the correct amount.Update 11/2010: As another reviewer mentioned, only 1-2 months after application all the hideous noises returned. Reapplication led to similar results. If you buy this, be prepared for frequent re-application at a high price. Rather than buying more, I will be trying the other Genie product mentioned by the other reviewer.Update 6/2012: Turns out the problem with my door was related to the design of the screw drive, not the lubrication. I have returned my review to 5-star. Per an Overhead Door repairman, my Genie/Overhead Door Screw Drive opener has a design flaw that creates a gap in the screw components when the parts are subject to cold temps. My opener only makes noise in the winter, so the explanation seems reasonable to me.
