I bought these grips for the ease of installation. The grips were great at the start they feel great on the hands and stay clamped nicely but after a few months the heat on the left hand grip stopped working. I would unplug the connector and leave it for a bit and then try again and it would start heating but would shut off after a few minutes. There has been no issues with the right side. Its too bad because other then the one grip failing these grips would have been great they do heat up quite well and are very easy too install.
Fast shipping as always. Bought these for my wife easy to install seemed to be well made. They worked well for her the setting buttons were a little hard to set but overall very good grip, first time I had used a clamp on grip was a little unsure but stayed tight for the first ride will update on long term.
