Review on AstroAI Inflator Pressure Compressor Accessories by Flavio Iyer

I bought one that works great and has an accuracy of +/- 1psi. The connection to the tire air valve was a bit tight, but worked fine. So I bought another one to use second. Connection to the valve was slightly better, but accuracy was poor - this sensor consistently under-read at 8psi. This is unacceptable. I'm increasing my rating from 1 star to 3 because the support team has been very responsive. They answered my email within a day and sent a brand new device for free within a week. Unfortunately the third at 2psi shows too much. I'll keep it and send a second one back.
