I have installed one of these on all equipment that has a battery / starter for 20 years. I pulled the first one I bought off a 25 year old lawn tractor, left to rot in the back yard, and it still worked! They are simple to use, easy to install, are used outside (not sure I'm supposed to but they get wet just fine for me), and maintain batteries exceptionally well. I've got a near perfect battery in a 20 year old tractor and 2005 automobile because I use this device fairly regularly. Three ways to install (zip tie, command strip, or screws. I have always used screws. Highly recommended.
