i am on my second one now first one had some malfunction when battery died few yrs ago and when got car jumped timer always turned off so bought bullet and got a new one. Today it was cold out and ye si have small battery in north dumb dumb ha, but jumped car from oem battery and now it seems to be acting up again not sure what it'd deal is but pretty dissappointed if the timer craps itseld of barrety dies bad quality

 

what greddy neglects to put in the instructions is that if you have to jump the car, disconnect it. Call them and see if they will send you another

 

great, glad they mentioned it, on side note what is cheapest place otr get mini battery from just the battery
