It's the most comfortable I've been on my bike since I bought it in April... for me that's amounted to slightly over 1600 miles. It made a HUGE difference in my fanny and my spine. It's going to take a bit more tweaking and by that I mean experimenting with just how much air is right for me.
I should mention that I had already done the seat lift mod with the nylon washers and longer screws. That helped a bit but wasn't the panacea for what was ailing me. :'(
I rode 60-ish miles each way which and spent most of the 4 hours between trips sitting in a meeting.
I followed the mfg's instructions then plopped the Med Airhawk directly onto the seat and didn't even bother to attach it with the straps. The cover has a rubbery bottom and it didn't slip at all. The Med is larger overall than the seat but the excess causes no problem or discomfort.
I'll try to get a photo posted.
I added one puff more air before climbing on for the ride home and I opted to add another couple of puffs once I arrived home in preparation for my next ride which may be yet this afternoon.
It's early and I'll let you know more as I log more hours, but I think it's going to make all the difference for me. I have wanted to ride up to see friends in Missouri and Illinois but couldn't conceive actually doing it on that seat. I feel a road trip coming on!!
btliquidations.com included a card in my package. it says they are located in Spring Hill, FL. Shipping was by USPS Priority Mail and included a tracking number delivered me via email. The initial USPS facility listed Miami.
Ride safe.
