AstroAI Digital Tire Pressure Gauge, 230 PSI 4 Settings Heavy Duty for Car Bicycle with Larger Backlit LCD Flashlight and Non-Slip, Black

If shortly – the Tire Pressure Gauge by AstroAI Digital is just a great tire pressure measuring tool. Some details are below. (Please note - TPG for a tire pressure gauge.) What do I expect from the “perfect” TPG? 1. Accuracy. 2. It should be convenient to use. 3. Reliable and durable. 4. Decent price. I’ve been using the TPG by AstroAI for more than 3 months and here is what I can say about it. 1. I don’t have handy the calibrated professional TPG to be able to state whether it IS accurate or it is not. But, this TPG displays values that coincide (less than +/- 0.5 psi) with two digital TPGs I own (one is the JACO SmartPro Digital Tire Inflator Pump’s built-in TPG and the second is my old TPG.) To my opinion, this is absolutely acceptable accuracy. Especially, if take into account the fact that a tire pressure may vary significantly depending on, for example, ambient temperature - at least 1 psi difference (for small and middle-sized tires) to each 10 degrees difference of ambient temperature. (E.g. you measure tire pressure in the morning or the afternoon.) 2. This TPG’s appearance is different from most of the others. (Instead of trying to describe what the difference is, I suggest that you check almost any TPG on Amazon and you’ll get what I am talking about.) But what is important, this TPG is convenient to hold in hand during measuring procedure and it perfectly fits valves of my car’s tires (no air leaks). Its display is excellent and the numbers are big and perfectly visible both on a sunny day and at night. This TPG uses two standard AAA batteries (non-rechargeable). I think that the only disadvantage of such a solution is that once in a year (maybe rarer) I will have to replace the batteries. Anyway, the alkaline batteries are usually safer than Li-ion rechargeable batteries. There is one feature that I want to specially mention. The standard behavior of the digital TPGs that I’ve used and read about is the following: after you checked the pressure in a tire, then TPG’s display keeps showing the current values for some time (usually around 30 sec.) and then, the TPG turns off. Checking the pressure in another tire within this time might be confusing. So I usually long-pressed my old TPG’s power button to turn it off and then turned it on again. So, smart folks from AstroAI asked themselves a simple question – how many tires we usually check during a single “session”. I bet that most of us usually measure pressure in all tires the car has. So, they implemented a simple, yet a brilliant option – when you finished checking the pressure in the first tire, then after about 10-15 sec this TPG resets the just measured values and gets ready to the next measuring. If you don’t want to check another tire, then in another 10-15 sec the display turns off completely, but if you want, then you have this time (10-15 sec) to continue. The second measuring will restart the TPG’s “timer” and it gets ready for the third one. So convenient! (Well, maybe this feature is not unique, but it is for me.) 3. Reliability – I’ve used it for maybe 30 times and no any kind of malfunction so far. I even checked the pressure 3 times in raw in one tire and got the very same values. As for this TPG’s durability, it’s difficult to say now, but it looks and feels pretty solid! So, if you don’t intentionally throw it or use it as a hammer, then I don’t see why it can’t last for years. ;) 4. Price - I think that it’s fair for such a quality device. Verdict: 5 stars – absolutely recommended! This is an excellent tire pressure measuring tool with a cool feature. Update (Sep 13, 2019): As the reviewer of this TPG, I’ve received the question this morning regarding the batteries and batteries discharge indicator. This prompted me to make short research… The result was slightly unpleasant – this TPG does NOT have any indicator of the discharged battery and the battery icon on the display is just a fake and does not change its behavior when the inserted batteries are seriously discharged. When the batteries are OK, then the gauge works just fine, but if you turn ON the gauge and it doesn't launch, then, most likely, the batteries are completely discharged. I considered decreasing the rating to 4 stars, but then I decided not to do that. The TPG still works just fine and this “incorrectness” may cost half a star, rather than the full one. ;)

Best tool I have purchased in a long time. Super easy to use and love the light for checking tires at dusk and after dark. We purchased one for all our trucker friends as gifts since we like it so much. Easy to read display, great value and always accurate.

The gauge is built very well and a descent weight for what it is and does. It's a solid weight. It was purchased for the rear wheels on my 05 Dodge Cummings Dually, but will use it elsewhere too. The gauge works extremely well on both the inner tire which uses the straight on chuck which requires the chuck to be pushed on and the outer tire uses the angled chuck which requires the chuck to be pulled on. Front wheels are no problem. Both chucks seal extremely well. The long metal rod rotates 360 which is very helpful. The LED doesn't stay on very long (as mentioned in other reviews), but you have a task to do so you push/pull, wait a couple of seconds while the chuck is on the valve, then remove the gauge from the valve stem, then look at the screen, no big deal. Screen is well light and the numbers are very clear, regardless of what unit of measurement is used. It measures in tenths of a PSI. I should have purchased this years ago. I have simulators on the rims (front and rear) and I cut out one of the five ovals so I could get my hand in there. You really can't tell much that one of the ovals is trimmed out. I have stock valve stems TR600 1-1/4" long, rather short, but stock. The angle of the chuck and the cut away simulator works great on the outer tire and reaching the inner tire as well. It did not work well until I trimmed out the hand hole opening of the simulator. The simulator adds about 3/8" to 1/2" of thickness and affected the angle of the gauge connection to the valve stem, but no problem with the opening trimmed out. I rely a lot of reviews of a product, so I thought I would return the same. A lot of writing for only a $15 - $20 purchase, but wanted to share my thoughts of the gauge. Again, the chucks seal really well. Just buy it and put is to use.

I would say it works good but here last few weeks it's been not resting back to 0 after a check other than thats it's been a good tire gauge

I would highly recommend this product. I’ve used one at work for over a year now. Very accurate, easy to use and best of all is that they use AAA batteries and not button watch batteries. Battery like is really good

This tire pressure gauge really works well, it’s accurate and it’s able to reach into your valve stems easily no matter what direction you come from. I highly recommend it.

Ordered these unsure if they would be accurate. According to my tpms on the truck, these read between .5 - 1.0 PSI difference in tire pressure, so not a bad purchase at all. Time will tell how durable they are, but seem to be pretty solid, and are easy to use. Great price as well. I ordered the two pack.

This is my third purchase of this item, so yes, I'm very happy with it and want to replace it. I believe my son and grandson have ended up with the first two, they are happy with this as well. It is a quality product, easy to use and I carry it in the car at all times. It is very handy to have.

Pressure gauge is accurate and easy to use. LED screen is easy to read and the long neck chuck avoids the user to have to get down on their knees to check tire pressure's. For proof of accuracy I compared the AstroAI gauge readings against a manual gauge and the pressure readings were the same.

مدري للان شغاله معي بس احس العيار غلط

Perfect Gauge

Très utile - surtout dans l'obscurité - pour obtenir la pression des pneus et les mesures sont en décimal aussi donc très précis. La raison qui m'empêche d'attribuer 5* c'est l'absence d'une soupape de décharge qui serait la cerise sur le gâteau.

Se siente robusto y de buena calidad
