Whatever happened to the days when everybody just trusted that this thing was the gold standard that everyone should use?
I used to buy those by the handful at bLowes; for some reason the brand they sold in buckets at the counter was very nice quality, but only a buck each. I'd test them on a large car tire when I got home, then toss any that didn't read the same, which was maybe 1 out of 10. I kept several on hand and gave one to everyone I knew who didn't have a tire gauge in their car. Dunno... saggy tires just bother me. (Sadly, bLowes stopped selling these; the pencil gauges they have now are much lower quality and much more expensive.)
Anyway, yeah, the Jaco clearly came out on top in the PF video, but the Merlin from HF was a close second, so that's what I've got in my garage. I had a HF coupon, and they're like a mile and a half away.
Sometimes the screamy PF guy encounters a Chinese alphabet soup brand on Amazon that tests really well, like the Ettenwolf tire gauge, but I have less than zero trust that what I get if I order it will be the same thing.
I do have to say that the delicate gauge unit banging around at the end of a stiff hose and facing the wrong way 90% of the time is the MOST annoying and useless possible form factor on the planet. Can't we do ANY better as a species? How about a model on a nice flexible Flexzilla hunka hose with swivels at both ends, and maybe a display on both sides. Maybe make the display so it detects orientation and flips as needed so the numbers are always right side up. How about something I could use one-handed? I would honestly pay handsomely for a better mousetrap here.
Also, checking motorcycle tire pressures is an even more ridiculously annoying task because you need a gauge with a right-angle chuck in many situations, and these are very hard to find. Often you can make an angled chuck work, but the common straight on chucks are right out. Getting a dingle-dangle-on-a-hose style to work on a motorcycle is a lot tougher than it needs to be.
And no, I'm not installing right-angle valve stems; I've seen way too many of those stupid things leak and break.
