Query: Just about useless

I bought this gauge from Target for around $11. While it will give you a quick initial reading, trying to do a second reading never works.Normally I put air into a tire and then recheck the gauge to see if the tire is still under-inflated or maybe over-inflated.With this gauge, you only get one reading. If you try to do another reading after putting some air in, it just reads 0.00, so you never know whether to continue filling air or to stop.This product is not recommended.
