Some Bend Pak and Direct lifts are made in China, I bought a 7000 Lb. rated Direct Lift drive on muffler type lift several years(10+) ago that had set outside in the snow for several years being stored before OI bought it. I haven't used it much except to store one car on it so I can park another one under it
The release valve started leaking shortly after I bought it, probably from gunk or corrosion from sitting in the snow so long
I will try to replace the leaky O ring this summer and hope it is repairable instead of having to replace the complete power unit
the guy I bought it from had bought 25 of them to use to store his cars during the winter, I could have bought a 2 post 10,000 Lb. rated but it was more money and I wanted the drive on lift instead of a two post
