Not much. It works as you would expect. It's an airbag for your ass. It feels a lot better than my stock seat. It changes the ride a bit because it lifts you a few inches. I'm doing a 1000+ mile trip a day as of today, so I'll update later. The only complaint I have so far is that it doesn't really last, but how can that be. It is attached to the seat with straps. My seat is tapered, so naturally it wants to slide on the cone. Oh, and the pump they include is really a waste. You don't have to "inflate". just blow in enough air with your mouth so it doesn't deflate and that's enough. He doesn't need pressure. In fact, I'm sure you probably don't want to pressure him because then you'd be blasting the cameras. I'm pretty sure it's like my inflatable kayak. Anything over PSI will load the material beyond its limit. "UPDATE" 1200 miles in the saddle for 4 days and I find it better than stick but my butt still hurts badly. I'll leave it because it's better than nothing, but if you're looking for a completely painless solution, keep looking. Of course, your mileage may vary.
