## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great.
*by M***X on December 8, 2024*

I have a parasitic drain on my truck battery that I haven't been able to track down. If it sits unused for 3-4 days I have a dead battery. Installed this before I went on a trip to see my grandchildren. Used it to cut off the battery before leaving and and the to cut the battery back in when I returned. Worked perfectly. Was easy to fit in place.

### ⭐⭐⭐⭐⭐ Make sure they're tight
*by R***. on October 22, 2023*

Work well on my dual battery setup. I can imagine times I'd need to rapidly disconnect batteries, and so I fitted this to both. I had charging issues, which I realized were due to not tightening this enough - tricky in the confined space I have. Make sure it's right, and it works very well.

### ⭐⭐⭐⭐ Check space before buying
*by Z***L on April 5, 2023*

I was hoping this would clear the small space, but alas, no. Item great and I have one for my s2000 that works very well. (Lots more space around the battery). My 2011 335i Convertible battery space was too small to accommodate. Very good return options.
