I have had three of them two suede one vinyl.
On three different bikes. In all cases the build quality was top notch, the materials all held up over thousands of miles off road (these were all on dirt bikes) and all made a huge difference in the comfort of the bike for long rides.
All I can say is waiting aside their quality is at the top and would stand against any other seat builder in my opinion.
I also have had corbin and one other I cant recall the name of and they too were a huge improvement over stock.
That said, you cant go wrong with these guys but there are alternatives that might work better in your individual case.
