I installed mine a month ago. I really like them.
One thing on the install that I found out... On the left grip, it fit so tight that I used and large socket and rubber mallet. The thing to pay attention to using this method is the orientation of the power button and how it lines up against the turn signal housing. When the grip was about 3/4 of the way on the bar, I noticed the grip was slightly rotated up but it fit so tight that I was unable to change the angle of the grip. All I could do was keep pounding it on while trying to rotate down. I ended up with the grip button slightly up. Since then , because of that, I have inadvertently pushed the power button while reaching for the turn signal. All in all not a big deal but I thought I should say something for future installs.
