1. I need technical bells and whistles, I freely admit. 2. CTEK was recommended more than 2 years ago and since then I love my charger because I have a feeling that it takes good care of my car and quad battery. 3. Although I do care about my tools, but just the sleek casing of the charger made it hard for me to handle it properly. The charger would often slip from my quad down and that has really bothered me, that has been dealt. The fit is very good and as you can see in the product photo, the bumper is made of more air than rubber. If both cables are once threaded, the Bumper nestles well against the edges of the charger. Not only that CTEK is now protected, but also the environment in which it is moved. As said before, the charger never wanted to lie there where I wanted it, that's different now.
