I had a J&S Jack when I had my Harley Ultra and Trike. It was a beast and did a great job with those heavy bikes. But, I sold it when I sold the bikes a year ago. Now I have a Honda Africa Twin which weighs about half as much as those Harleys and I miss the J&S. But, thought I would take a chance on the Vevor and I am pleasantly surprised. It was pretty easy to assemble and the few times that I have used it I was happy with its performance. One really nice feature is the very slow release to drop the bike down. No panic like I had with the old jack. The only problem I had was the safety catch which was bent out of shape probably due to shipping. It took me a while, but gentle persuasion with my bench vise and some leverage tools worked. I had to fiddle with the little spring clip that holds it in place when lowering the bike, but that seems to be working now. All in all, a good purchase at a very fair price.
