AstroAI Pencil Tire Pressure Gauge 2 Pack (10-75PSI, ±2% Span), Air Pressure Gauge for Tires, Stainless Steel Body, and Metal Made Nozzle 3 Measurements for Cars, Bikes, Vehicles

I recently acquired the AstroAI Pencil Tire Pressure Gauge, and I must say, its purely mechanical operation is a significant advantage. In an era where nearly every device relies on electronic components and, consequently, batteries, the simplicity of this gauge is a welcome change. There's no concern about dead batteries at an inopportune moment, or the potential for electronic malfunctions that can plague digital counterparts. It consistently functions, providing immediate readings without the need for power.The design of this gauge is refreshingly straightforward. Its "pencil" form factor is slender, making it exceptionally convenient to store in a glove compartment or a compact toolbox without consuming excessive space. The absence of complex features or settings underscores its primary purpose: to accurately measure tire pressure with minimal fuss.Regarding its performance, the accuracy of this AstroAI gauge is noteworthy, especially considering its accessible price point. I compared its readings against a professional-grade, calibrated gauge, which represents a significantly higher investment. The AstroAI consistently delivered readings within 1 PSI of the more expensive unit. For typical automotive maintenance, this level of precision is more than adequate. It capably meets the requirements for ensuring proper tire inflation, a critical aspect of vehicle safety and fuel efficiency, without the need for specialized equipment.I am not a Formula-1 member of the pit team and this tire gauge works for me!

AstroAI’s 5 pack pencil tire pressure gauges are exactly what I needed/wanted. After misplacing my last one, I bought this 5 pack for the price of one at the locally, so I could put one in every relevant location.The gauges bodies are made from real metal. They work correctly (compared accuracy to a digital gauge).Product comes with 4 schrader valve caps.Product was delivered on time.I would recommend the AstroAI tire pressure gauges to anyone needing a convenient, easy to use product.

These are, at least initially, reasonably accurate. The price is right but they seem a bit flimsy.

This is a basic (square shaft) pencil type air pressure gauge with 2-psi gauge read increments. It is a very good value for the price. These gauges perform very well. I've used Automotive pencil type air pressure gauges for 40 years now. These seem to be identical in quality. Only time will tell how these hold up for accuracy and reliability, particularly here in the Great Lakes region (Lake Erie / Northeast Ohio, USA). Initially I am definitely pleased with the quality. Having four new plastic valve caps included is a nice bonus.Most people know very little about the value of maintaining correct vehicle tire air pressure. For such an inexpensive tool, this pencil gauge set saves money in the form of consistent optimum gas mileage as well as promoting more uniform tire treadwear.

Nice tire pressure guages !!! No fiddling around trying to get them held on the valves straight, they have a deep head on them that fits right over the valve stem and stays on there securly !!!Easy to use, just ordered a second set !!!

Works great. Perfect to keep in the glove box.

2 for $5.26!!! Are you kidding?! They work great & took about 14 hours for delivery. They are cheap but EXACTLY what I wanted!!

not so accurate
