I couldn't agree more. I ordered a seat for my Suzuki dual-sport just after Christmas of '08, called a few days later to ask about a change in the shape of the foam, to make it more flat. I talked with an employee first, who told me my request wasn't needed. Then I e-mailed my Corbin rep. with the request, then called and talked with him the next day. He said they would make it as I asked.
It arrived in about 6 weeks, standard dimensions. Going on their claim of great customer service, and web site request for my inseam, height, etc. for proper seating, I tried the seat, found it slanted forward so much I had to fight to stay away from the gas tank.
I e-mailed their customer service 3 times between Mar. 26th and Apr. 3rd; got no response. The Better Business Bureau filed my complaint with them, but let me know that Corbin has responded to only 20 out of 38 complaints the BBB has handled.
I hope this posting keeps someone else from buying from Corbin in good faith. In my experience, once they've got your money you're on your own. Expect nothing, because that's what you get.
