I purchased a Peak 12v programmable tire inflator ( model PKC0VG ) from a local hardware store 1.5 years ago. It worked once and when I retrieve it from the trunk to fill a flat, it failed to work. Because this unit sat on the shelf at my local hardware store for more that two years Old World would not warranty the unit. Please do not purchase anything from this company. It's Chinese junk !!
