I ordered this heated hand grip kit for my new Ariens 28" snow blower, it took about 45 minutes to install. The instructions were pretty good but I'm very mechanically inclined. I fired up the blower, flipped the switch and within 30 seconds the grips started warming. I would say within two minutes they were really nice and warm. The kit was made well, the wires were easy to run and keep away from pinch or rub points, this will make the Wisconsin winter much more bearable. I will always order from Jack's, the parts are all OE and the price is the best.
