Word of note...Costco carries a similar unit for about $15-17
Costco unit includes a flashlight, portable digital pressure guage, various connectors, Cigratte Adapter powered, and 250psi analog guage. (batts included for digital guage and flashlight....flashlight can also be powered by compressor when docked.
One comment....250psi is a tad extreme for for an analog guage.....forget being accurate on car tires...difference between 20psi and 40psi is very hard to read.
