Easy to fit. Open ended to fit all bikes. Fits motorcycles with 22mm bars. Waterproof switch which can be mounted either on the handlebars or fairing. Anti split / anti perish rubber. Only 1.5 amps consumption. Quality assured. MCN said, The grips were simplicity itself to fit. Slide the grips on the bars, connect the wires to the battery and hey presto, hot hands. The warm setting keeps the worst of the chill at bay and makes a big difference on the coldest days. They're made of rubber, not plastic, so you will still get good feedback, and they aren't bulky like some other heated grips.
