Bests & Worsts Reviews from Amazon

I sincerely looked forward to having this product as a universal backup for most car issues one encounters on the road. Fortunately amazon was quick to address the issue when I found out the compressor function didn't work at all. My car was still in my driveway or I may have been on the side of the road in freezing temps finding this all out. The other functions may work (haven't tested them) but the compressor doesn't, it sounded as though it was but continuously shut off after adding only a few pounds when tested on three separate tires from two different vehicles (shut off at about 26 - 29 lbs). The gauge was also incorrect when tested against two very accurate tire pressure readers, it read 34 lbs when the pressure was still under 30. I'm not the only person this has happened to.. The item should be recalled.
