These heated grips are well made and are readily obstruct the original handlebar. On the sleeve of the throttle slight ridges with a glove on me that I had to remove with a file. The included super glue holding the handles then but after mounting bombproof on the handlebars. This instant adhesive can be regarded as an advantage and as a disadvantage: + Keeps super + Handles are no drying time can be used immediately -are top handles, they are on it; no longer possible after adjusting So make sure to first and so the position, without consider adhesive. The adhesive can also bring well with a syringe (with needle) under the handles because it is thin as water. The function is bomb! At the highest level burn the fins :-) The five stages of the switch are well matched and the Battery Saver saves determines again the battery! No relay for the battery needed, but you can make. Would I buy it again! Oh yes, very cheap!
