Title: Very Inaccurate
Review: Upon receiving the Slime 2021-A Tire Gauge I tested it on 4 tires of a known air poundage which was 40 lbs (checked by two other gauges). The Slime 2021-A gauge read that they were at 80 lbs. so obviously something is wrong with the Slime 2021-A. I'm glad that the other reviewers had good results but mine are so bad as to render this gauge to be useless and I expect to send it back to Amazon.
