   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. ;)Read more

   I have had this pressure gauge for some time now and used it multiple times. I like that it uses standard AAA batteris, has a large back-lite display that is accurate to 1/10th of a pound. I haven’t found the LED for illuminating the valve stem useful as of yet as I’ve not needed to check tire pressure in the dark. I have another digital pressure gauge of a different brand and the AstroAI Digital Tire Pressure Gauge is everything I didn’t like about that other gauge. I’ve tested the same tire multiple times just to see if I got any variation in the test results and they were the same after multiple tests. This gauge works well on my automobiles, but as for my motorcycle, the brakes interfere with getting a straight shot at the valve stem. If they were to re-design this gauge, I’d suggest to put an angled head on it for tighter spaces. Aside from that, I really like this product.Read more

   Accurate, easy to use and read, and it feels durable. The best part is that this uses AAA batteries instead of coin batteries. My previous similar pressure gauge (a popular item on amazon), it required not one, but two different sized coin batteries! When the batteries ran out (~2 years of seldom use), I just tossed it in the garbage can as I wasn’t going to order two sets (which I have to typically buy in bulk when it comes to coin batteries). The batteries in these should last at least a year but when that time comes, I can readily replace it.Read more

   I keep buying tire pressure gauges because they’re barely more expensive than replacing the batteries on the old one when they die. I have probably owned close to 2 dozen tire pressure gauges and this ranks as my favorite consumer grade gauge. It feels almost industrial, it’s accurate, and most of all it gives you the tire pressure reading to the 10th (e.g. 32.25 rather than just 32). So far it’s lasted a few months and very consistent. Build quality wise, it has room for improvement such as the neck being attached to plastic which could break off with stress or a few drops, but all the consumer grade gauges suffer from this flaw. I rate it 5 stars and say it’s definitely a buy!Read more

   My previous digital air pressure gauge broke about the third time I used it–the nozzle was plastic. This one is much sturdier, with a metal nozzle that points straight ahead, which makes it easier for me to get a good seal on the valve stem. And unlike my old one, this one stays on the reading you prefer (psi in my case) and doesn’t require you to cycle through all the others every time you use it. Also, it takes AAA batteries that are easy to change. Interestingly, after you check a tire, it holds that reading for about 30 seconds, about the time it takes to put the valve stem cap back on and move to the next tire, then resets to zero for the next check. My only complaint is that the gauge doesn’t have a pin to let a little air out of the tire when necessary.Read more

   I’ve never owned a digital tire gauge before. This one by AstroAl is really nice. It fits nicely into the palm of my hand. The display is lit and has large digits, so it’s easy to read. Also, some tire gauges are difficult to seat properly without air escaping. Not this one! It’s so easy. Just push the power button to turn it on and then press the unit firmly onto the valve stem. Almost instantly a digital reading appears. It even measures to the tenth of a pound of pressure. The display will turn off by itself within a few seconds, or you can press and hold the power button to turn it off. I really like this gauge and would buy again.Read more

   Tiene 3 libras de margen de error, es decir si quieres poner tu neumático a 30 libras reales, el medidor debe marcar 33 libras.Read more
