I presently have several of those "greenies" in use, including one on my 2007 Chrysler Pacifica. I have had 2-3 of them corrode a little over time, I just toss it and put a new one in. On the old cars I don't drive them that often so they work well for me. On the Chrysler (my daily driver), the switch works fine. I put it on the Pacifica because the battery caused a lot of corrosion ( I tried lots of tricks to stop it, nothing worked ) and it ate the original clamp. I put the greenie on there and used the hole in the end to bolt on the original cable. When the battery died after 6 years I put the whole set up on the new battery, it's been over a year with no problems. I know they are cheap but my experience has been OK. I do keep a close eye on the cars that have them in use however.
