I have the Utopia, but have not been overly impressed with the quality. For one thing, the bolts that secure it to the seat pan are only 1/4". After a trip up to Lake Superior last fall, I noticed that the seat seemed to be loose. Inspection revealed that the bolts had both sheared off, probably from bumpy roads. After removing the broken off portions, I drilled and tapped the mount for 5/16" high strength bolts and all seems to be good. The second issue is that the mount on the pad itself was off center, and no way to move it. I had to make a wider bracket and use washers on one side to move the pad back to a centered position.

So a little re-engineering and it works well, wouldn't ride without it.
