I'm quite picky about keeping tire pressures right where I want it. Naturally, I check PSI at least once a month, and whenever we have a sudden temperature drop. I've had plenty of vehicles with onboard PSI read-outs, but those are by no means 100% accurate. So having a good tire gauge is very important. My current "go to" gauge was theAccutire MS-4021B Standard Digital Tire Gauge. It was basic, as it only provided the PSI, no LED light, buttons, etc. But it worked. I never had issues with getting a seal. The one I wanted to be my favorite is theAccutire MS-4350B Programmable Digital Tire Gauge. That had all of the features I liked such as a light, back-lit display, memory for tire pressures, etc. But, it wouldn't always get a good seal with every tire. Some worked well, others, not so much.Then along comes the Amazon Digital Tire Gauge. It basically combines all of the features I want/need, and then some. You have a swivel head (no more awkward angles), air-bleed knob on the back, back-lit display, LED light, and memory that will let you store front/rear tire PSI so you don't have to dig around your owners manual or check a dirty door jamb.I was skeptical it could do everything it claims, and do so reliable. So I've been using this for about a month between various vehicles and every tire I could get my hands on to get a solid feel for it. After all, not all air stems are created equal. But I'm pleased to report that it's been working perfectly. It always gets a solid seal and I don't have to keep moving it around to prevent air leakage.Pros:* Rotating head* Back-lit LCD* Programmable PSI for front/rear* LED Light* Air bleed knob* Bonus: It comes with a case.Cons:* The case could be sturdier so the LED light switch doesn't accidentally get squeezed.It's rare when I don't post a real "con" for a review. I naturally assume there is always *something* that could be improved on or isn't working perfectly. In this instance, the only slight negative is the free cheap case. And that's not even really an issue for me. :) But it sounds like Amazon really did their homework on this one. I consider this highly recommended.
