I work at a tire company managing the tires of a large commercial fleet, I've used crappy spring gauges for a few years but moved to digital because they never stay accurate for very long. Previous digital gauges I have used had several disadvantages leading me to constantly try new ones to see if there is a better one. This gauge is pretty much perfect for doing a ton of air checks on big trucks. Some improvements on prior digital gauges I've used: - This gauge uses AAA not coin batteries, huge plus! In winter use Energizer Ultimate Lithium rated for -40c! - Fast Startup when you push the button - Little light is actually pretty useful when checking inner duals, is a handy indicator to tell if the gauge auto shut off right as you go to check a tire also. - Auto shutoff gives you ample time to get the caps off and check pressure, timer resets every time a reading is taken so you only need to push the button once to check the whole unit. - Display is huge and bright, numbers do fade when viewed from a very certain angle but very clear most times. - We test our gauges weekley and it has been spot on for the few months I've used it. - Display slows down a bit in the real cold but works just as well. Live in Alberta & its been in the -20c range already.
One caution is the metal shaft screws onto the plastic gauge body, this joint is a weak point and my first gauge ended up cracking, (possibly due to the cold). Its fine for normal use, just don't put unnecessary pressure on that joint. I contacted the company and they sent a replacement gauge right away so it's nice to see they support their customers.
