I bought this for a hard to open sliding glass door. I am a tenant and the landlord will not spend any more money on this house. I sprayed it with WD-40 but that only lasted a few days. When it came in the mail I couldn't wait for you to try it. I cleaned and lubed the track really good, man what's the difference. The door slides easily. The reason I gave it four stars is that it also won't last as long as I would have hoped (girls stop giggling at this comment). This takes about two weeks before you have to reapply. Overall this is a good product that comes in a stick making it easy to use. I just put it back in the storage box. If this review was helpful, please click Yes below.
