Some savings compared to other brands of clamp weld adapters. But even with a flat jack saddle, the Byenins slots aren't long enough to use Byenins alone and you just need a jack that comes with other settings. Or you can scratch the bottom of the car. I went to Dicks and bought a $2 hockey puck, put it in the saddle and that's on top and everything worked fine. So only $18 versus $50 for others. For $30 or so it's not worth using the puck and Byenins so they buy another company with the puck included. Having saved $30 on something like this, I don't mind a two-part approach. 4 stars because I had to buy something else everything was ok.
