UPDATE 8/11/18The grip heaters are still going strong. Know, however, that the ATV is used for work around the property and plowing snow in the winter, so actual hours are pretty low. The grips have worn (smoothed) just a little bit more than I think they should have under the use they've seen, but still a great product, in my opinion.EDIT 5/29/14Using these grip heaters over the winter has solidified my opinion that these are a "must-have" for any ATV used in cold weather. The heated rips coupled with good leather, insulated gloves kept my hands comfortable during a few several-hour plowing sessions in sub-zero temps. Even in mid-fifties weather this spring, it's nice to have them on the lower setting for just a little added warmth with light gloves.ORIGINAL REVIEWAs others have stated, these grip heaters WORK. The separately-set grip and thumb-warming elements allow for adjustment of each. (So far, I usually end up with thumb one notch higher than the grips.) Even on a "cool" rather than "cold" day, the heat is a welcome addition. Time will tell how they handle single-digit temps while plowing snow, but I have little doubt they'll be effective.Like others have suggested, I chose to connect the system to a key-switched power source. This provided two important things: 1) Automatic shut-off when turning off the ATV, and 2) A fused power supply. On my 2008 Grizzly 450, I used the accessory plug in the right-side fender. ...And don't worry, the system returns to the same settings it had before power was removed.Installation using the 3-times-applied WD40 worked like a charm, with the grips sliding on effortlessly. I will caution users, however, to twist the grip to the desired position immediately upon installation, as waiting even 5 minutes will result in a grip that is almost immobile.Since I'm rather particular, for the left grip, rather than having the wire run around the switchgear, I removed the switch assembly and, using a Dremel tool, cut a small relief notch in both sides the plastic housing. This allowed me to run the wire *through* the switchgear, instead, making for a cleaner installation.If/when we add another ATV to the herd, these grip heaters will be one of the first modifications made.
