IBS easylift snap davits

[snowbird30ds]

Any experiences with IBS easy lift snap davits sought, are they any good and do they last.
Any info greatfully recieved, I can't bring myself to pay weavers prices.
It's for a pvc dinghy on the bathing platform of a princess 30ds.

They were fitted on our new to us Beneteau oceanis 40. I can stow our dinghy in a few minutes. Dead easy to hook on and off.
I fixed the pads onto my own dinghy using the proper pvc glue. They have lasted 6 months with no problems.
You still have to lift your OB off and stow it. Job is made easier as the davits make the dinghy into and extended stable platform.
Acts like a big fender when reversing into dock.

Other question is do the different make systems use the same centres on their pads?
I've been looking at the aliexpress offerings which look good but the pads look inferior.
