Well I’ll make this short, skip buying this.
Oh you want more info? Ok, well I dropped my Accu-Gage on the ground and the reading seemed off. In my local shop they had this available and they recommended it. It has one nice feature and that is about it.
The nice feature is the head rotates 360°.
But what frankly is annoying about this thing is that it spills a ton of air when putting it on a presta valve, which is quite annoying on mtb tires where you are dialing in 0.5-1 psi. Oh and the biggest disappointment is that it doesn’t read less than 1 psi, I ride a 27.5+ tire where I routinely ride 16.5 psi. Oh and the bleed valve does not update the reading.
This is junk and I wish I could return it. The Meiser Accu-Gage is 100x better.
