### ⭐⭐⭐⭐⭐ It works!
*by P***U on 11 December 2024*

Something so simple & cheap has fixed it! 2 new battery's & the AA looking at it & could not find what was draining my battery.Its been absolutely brilliant.

### ⭐⭐⭐⭐ Fits on the negative post
*by P***L on 14 June 2024*

If you're looking to isolate the positive post, this one won't fit on the positive as it is sized for the slightly smaller negative post. Even though isolating the negative is typical on car disconnects, this ought to be mentioned in the description somewhere as some may be looking, for whatever reason, to isolate the positive side.
