So i was looking these tire gauges up online and apparently they were a promo item that you got if you spent $100 or more and they didn't really get given out enough or something so they're selling them for below cost cause I got mine while i was waiting for the lady to get a part number for a bleeder valve and i noticed this for 10bux! the lady told me that they were actually losing money on those because the cost of them was $11.35 or something WIN!
They have a 1 year warranty and fit nice and snug in the case =)
