Loved it, now HATE it. Worked great till it stopped boosting anything, I returned it and got another. Now the second one just stopped jumping anything and I am outside my return window. Are you kidding me! Several hundred dollars out the window. My $69.00 booster is still working after a year. I've had this thing since September 2017, and it is now January 2018. Less than 4 months for hundreds of dollars!!! Unbelievable.
