WirthCo Engineering Battery Doctor Knife Blade Switch For Top Post Batteries with 5/8" DIameter Post is rated 3.0 out of 5 by 2.
Rated 2 out of 5 by from Battery disabler Product flemsy and screws work loose and plastic acts like it wants to break.
Date published: 2015-10-16
Rated 4 out of 5 by from Great features Great features, but the rivets allow movement which will lead to premature failure. I drilled out the rivets and replaced them with bolts which can be tightened from time to time preserving good electrical connection.
