Keep it tight or no-go.

Worked fine for a few weeks then no juice to start. Tightened and worked ok. Keep it clean and tight regularly. did not like it... it broke while installing it!

Pros
  • Anyone have old car in garage for long term storage or weekend car need this.
Cons
  • did not like it... it broke while installing it
