The looks and comfort are great. I could not get the holes for installation to line up, no matter how hard I twisted and pulled on the unit. I eventually overdrilled the holes on the unit to 1/2" and then got it on. Not the end of the world, but a bit more work to get it to fit than I expected.
I put this on an 05 RX1 so I can have our young kids ride with us. It works very well for smaller kids, up through 10-12 years. I would not ride an adult on it, as the rear shock wasn't meant for that amount of weight. It's pretty easy to install and durable. I would recommend finding a pair of gaiters that you can mount on the hand bars to keep their hands out of the wind. The styling is also pretty nice, I have seen other seats that look pretty cheap. This is all one unit, very sturdy.
