worked well as one of my 6 volt batteries couldn't keep up with the other 5 volt batteries. After about a week and a half, everyone had the same readings and performance improved significantly. I later realized it wasn't a service tool, so I uninstalled it and bought a "Save Battery 2365-36.36 volt" charger/desulfator/maintenance tool for my need to be a Florida snowbird , worked and hasn't been used for months All the reviews I've read said others have been in the same situation as me and it worked great. it doesn't remove anything from pulsetech, but that was missing. If you were going to use your car all year round I would highly recommend it.
