AstroAI Digital Tire Pressure Gauge 200 PSI, Industrial Tire Gauge Calibrated to ANSI B40.7 Grade 2A (±0.5%), AAA Batteries, for Light Trucks, Pickup Trucks, SUVs, Cars (Black)

Cool little device, does what it says it will, makes the checking of tire pressure more certain than the guess work of older gauges. Lights up on use, makes it easy to test in all kinds of conditions. Two AA batteries means easy to replace, no need to charge, no button batteries, etc. Feels a bit lightweight, so not sure how long it will last, but it's a great little stocking stuffer for the car enthusiasts in your family.

Give an accurate measure of tire pressure. Easy to use and with the digital readout you know the exact tire pressure

For years I have used either one of those “stick-pen” type tire pressure gauges and then transitioned to using a round dial gauge type tire pressure gauge, but I recently bought a car that has staggered tires (different size tires on front vs rear) and started to obsess about maintaining more accurate tire pressure, so I ordered this 150 PSI AstroAI Digital Tire Pressure Gauge with Replaceable AAA Batteries. A couple reviews noted that it was difficult at times to maintain a proper seal when taking a reading, although I have had zero issues with this digital gauge having used it multiple times. I really like the relatively large and easy to read tire pressure display, and the backlighting really helps in Low light-level situations. The Industrial Design (styling) is very contemporary and has a quality appearance to it, as well as a nice ergonomic handle that fits well in the hand. The tire pressure gauge takes near-instant readings and is highly accurate within a reasonable tolerance. I have used it to take reading on my bicycle and several of our cars, and it makes life a little easier not having to try to read/interpret the old non-digital tire pressure gauges that I used to use. I gave this 4 stars, but actually it’s more like 4 and a half stars (just shy of 5 stars) as it’s almost perfect. While this digital tire pressure gauge comes setup to take readings from the standard Shrader-type valve fittings (found most everywhere) …it also comes with a metal adapter that you can fit over a (less common) Presta-type valve so that it can be used in almost any situation. I imagine the little metal adapter could easily get lost over time since it is just “loose equipment” , but feel that it would have been great if the manufacturer had provided a storage slot with detents molded into the tire pressure pistol grip to hold the adapter for future use. Additionally, I feel that the glossy hard plastic pistol grip is just a bit slippery to hold, and could benefit from using a textured surface to promote better grip. And finally, the pistol grip has a thoughtfully provided lanyard slot at its base…but no lanyard provided! A lanyard could be used to not only provide additional means to retain the gauge, but also have the manufacturer’s logo on it for brand identity. I appreciated the reasonably understandable instructions and feel that overall, this is a really decent digital tire pressure gauge (especially for the price-point) that will make life easier for anyone that needs to quickly and accurately check tire pressures. I would highly recommend it.

Works great, accurate.

Is it silly to say this tire gauge changed my life? Trust me! It did! It fits in the glove box and reasonably priced too. Getting my tire pressure right is really easy using this thing. Once the gauge is engaged and no air is leaking out, the pressure is displayed in the little window and is visible day or night. Just zero it out between measurements. Your tires will thank you for your attention to detail. I am grateful to know the tires are properly inflated. You can use this tool in the dark or in noon day sun. It comes with an adapter for bicycle tires… This gauge uses regular aaa batteries - no coin cells! My hubby and I really like this gauge! Now we need a compressor to service our tires in our own shady driveway instead of going to the service station.

Exactly as advertised, easy to use, works well, good price!

I had one similar that went dead when I needed it. You couldn't change the battery. I love this tire gage. You can change the battery, 2 triple A batteries. You can read the screen after you take off the tire and it's accurate.

Compact and Accurate Tire Gauge – AAA Batteries Make It Handy This AstroAI digital tire pressure gauge is small, compact, and features a backlit LCD with a non‑slip grip, making it easy to store in a glove box or pocket. It measures up to 150 PSI across four settings (PSI, bar, kgf/cm², kPa) and powers on with a single button that also switches units. The replaceable AAA batteries can be swapped without tools, and the gauge gives fast, precise readings once a good seal is formed on the valve stem. Occasionally it takes a second try to avoid hissing and lock in a stable reading, but once seated it displays pressure to the hundredth place reliably. The plastic housing feels smooth and glossy, though it can become slick with wet hands despite the textured grip. Overall it’s an inexpensive, functional gauge that works well for RV, truck, and bicycle tires when you keep the AAA batteries on hand.

Son muy buenos, lo compramos para calibración en una estación de servicio de gasolina y aguantan muy bien el uso constante, lo recomiendo ya que son precisos y no quitan casi nada de aire, pantalla visible y facil de usar.

İki senedir sorunsuz kullanıyorum

El interruptor del manómetro funciona de forma errática, de manera que la mayoría de las veces no enciende ni permite cambiar las unidades de presión. En condiciones normales, podría pensar que es una unidad defectuosa y hubiera solicitado el reemplazo, pero el embalaje tiene todo el aspecto de haber sido ya utilizado y devuelto, habiendo pasado sin más a la cadena de distribución. Eso no es una política aceptable por parte de Amazon.

Artikel in Ordnung,ob er genau ist kann ich noch nicht sagen.

Super convenient pressure checker Very simple to use and a helpful feature where there is a light at the nozzle that helps a lot during night time Accurate reading too
