AstroAI Digital Tire Pressure Gauge 3-300PSI Calibrated to ANSI B40.7 Grade 2A (0.5%), Backlight and Flashlight, Presta Valve Adaptor Included, 4 Units, AAA Batteries, Orange

I was replacing an older digital tire press gauge that had a small and very hard to read display. This gauge has a very large and bright display which is easy to read. Plus it has an LED headlight near the tip of gauge which illuminates the tip and tire measuring point for reading in a dark environment. It uses one AAA battery, I would never buy a gauge that uses the coin size batteries. Most people have AAA batteries in their possession for other uses such as TV remotes but the coin size are special application and expensive. This gauge is also very easy to use, one press to turn on, another press if you want to change the measurement units, Press for three seconds to turn off and it turns off automatically after about ten seconds. The gauge was so good I purchased a second one for my other car. Would highly recommend. Just in case I keep a manual pencil type tire pressure gauge in each car and an extra AAA battery. I think I’ve bored you enough, over and out.

This digital tire pressure gauge is simple to use and very functional. The large, lighted digital display makes it easy to read, even in low light, and it appears to be very accurate. It also has a forward facing light to see the valve stem at night. Great value for keeping both car and truck tires properly inflated.

I was looking for something with a wide range for checking tire pressures for passenger cars to Semi trucks without spending a small fortune or purchasing multiple gauges and gave this a try. The quality of the build is good for the price but the usage of the term "accurate" is wrong in the advertising. The device has good reproducibility on measuring pressures but the accuracy is very poor but consistently measures pressures 3psi low compared to a $100 digital racing gauge that I own (I purchased 2 units and they read exactly the same so manufacturing is consistent). Just because something reads to the tenth of a psi doesn't make it accurate and in this case if they cut the pressure range in half for the device they could drastically improve the accuracy of it. Because it has good precision I was able to calibrate it and have simply written the offset on the outside of the gauge and have no issues with using this as my regular gauge for checking tire pressures. I.E. the gauge reads 29psi = 32 psi actual My concern is for those that use these not knowing that you are over inflating a tire on a passenger vehicle well above intended manufacturer tire pressures (if you don't account for the offset) resulting in less tire tread contact area.

Very easy to use with angled head. numbers are very easy to read, even in low light areas. Seems to be highly accurate. Flashlight is a real plus!

Easy to use it works well!

Large display. Easy to use.

This tyre gauge has outlasted my other gauges by far. I love the large easy to read display. The readings are pretty accurate when checked against other pressure gauges.

Works well

Very simple to use, easy to read with back light, readings are accurate and will even display 0.5 lbs increments.

This is a big improvement over my well made but somewhat hard to read analogue gauge. Simple to set (psi/bar etc), easy to position on valve, seems well made, clear read out and simple battery change (in the future). Great value. Highly recommended.

Ein sehr praktisches Gerät mit präziser Druckanzeige. Durch die abgewinkelte Form lässt sich das Ventil am Rad in jeder Position leicht erreichen. Die eingebaute LED hilft beim genauen aufstecken auf das Ventil, um während der Messung so wenig Luft wie möglich aus dem Reifen entweichen zu lassen.

it is not heavy duty , starts to leak after few uses

Es un producto muy útil muy exacto en sus mediciones
