I’ve owned this for awhile now…BUT I’m CONFUSED as to what the “reading” is/for WHILE inflating WHILE the handle is compressed? When you let go that’s supposed to be what your tire’s PSI is currently at. So, what is the other number WHILE inflating? They don’t match either…

[@ReviewsUnscripted]

Not official non engineer thoughts on this from me... When the air is flowing through the nozzle at a high volume filling the tire the pressure sensor can't accurately read the static pressure in the tire. That is my best amateur analysis.

Same question, I believe it's the psi pressure going into tire? Mines was all over the place

@@finessedabest9341 my 2.5 gallon air compressor at 80psi was reading around 42 psi consistently when I was playing with it. Haven’t used it yet tho

[@larryhudson3930]

How well does it connect to the tire valve stem?

[@ReviewsUnscripted]

I use it regularly and have never had an issue. Have you had issues with that before?

[@larryhudson3930]

Yes, but I think it was me and not the device.@@ReviewsUnscripted

Can you calibrate the gauge? Mine is reading 5 psi off

[@ReviewsUnscripted]

Oh! Interesting question. I'm going to guess no. Did you contact AstroAI?

[@D1G1TALSYNAPS3]

Mine recalibrated while on the tire and now it’s 100 off
