I went to Brookstone store in a mall nearby. I was surprised - in online they show Accu Gage picture in dial but in store the guage is sold under Brookstone brand and dial is white color in online picture but black color when I bought. I was excited I got a good deal and I went to gas station next day morning. I brought my old digital guage also to check accuracy. I started with driver side front tire - Brookstone showed 31 psi reading and my digital showed 29.5. I said what the .... I saw chuck wasnt secured tightly to hose ( attached to guage ). Tried again this time it showed correct reading. I connected air compressor hose for inflation, dial went upto max ( 100 psi ) while inflating and when I stopped it showed 36psi. I tried digital it showed 33psi. I tried again brookstone, it showed 33 psi correctly now.
Now went to other tires, chuck wont secure properly to tire valves - hissing sounds or dial staying at 0 psi. Good news is Brookstone guy said - whenever you have a problems with it, bring it back, they will replace it for free. Tomorrow I am going to give it my friend for trying just to make sure it wasnt user error.
Now my questions to u guys who bought "actual" Accu-gage EZ Air.
1> Does chuck secure properly to tire valve ? Do you also get hissing sound ?
2> Afer inflating tire, does guage show accurate reading without removing chuck.
3> Did anybody compare readings with Accugage with other product ?
If my friend is also having trouble with it, I will return it.
