Surpised to find how accurate these are

I was considering a dial-type gauge. Truth me told I had 2 with solid brass fittings; my son, I think, killed one by using it on truck tires with nearly double the max pressure, and the other seemed to differ considerably leaving me to wonder which was more accurate. I decided since we seem to lose and abuse these, I'd spend less. I checked these when they first arrived and found them to read the same pressure. I was very surprised to find how accurate these are. We recently had our car serviced and I asked the mechanic to inflate the tires to the same pressure and check with an accurate gauge. I checked all 4 gauges against that 40 PSI and found these were spot on. My dial guage was off by 6 PSI! (like 15%), and the older pencil gauge somewhere in between. I'll mention 2 things that do give just a little pause. 1) These weigh maybe half what the much older pencil gauge weighs - lack of mass doesn't necessarily make them less durable - and certainly doesn't hurt accuracy. 2) The range of these goes up to 75 PSI (as in the description) - so 40 PSI, a bit higher than the placards on my cars suggest, is near the middle of the range. That means the number are a bit smaller than my other gauges that haxed out around 50. That said, if you want to check the "doughnut" spare you might well have, this will likely work for you. I think mine are supposed to be at 60 PSI, and I think I've seen some a little higher - making the range of this quite approriate for car and light truck tires.

Good little gauges at good little price!

Looking for tire pressure gauges for our vehicles and our daughters. There were many choices, some high tech and expensive. The AstroAl Pencil Tire Pressure Gauges were just the right price, especially when having to buy five!! They fit well in all the glove boxes. Easy to use, easy to store. Many cars have the tire pressure sensors but they aren't always accurate and don't always last. This gauge is a nice backup! And for cars that don't have it, a necessity when the tires just doesn't "feel" or look right! Very inexpensive but useful!

Seems to work as advertised, and seemingly good value

I compared all 5 on one tire and they were reasonably consistent. Probably not perfect if great precision is required, but suffices for my car/bike needs. Importantly, it goes high enough for both (car for the small spare), where my older ones didn't go high enough. Will note that someone else had commented these are not metal, and I would agree that the cylindrical body is not likely metal but plastic (I'm basing that on overall weight, and by comparing the center of gravity of my old one vs. these new). The head however does seem to be metal. Not sure the body material makes a "material" difference though!

Loved that it’s a two pack.

They’re easy to read and utilize. As far as accuracy, I really can’t comment, as I have nothing to compare it against, or to verify the accuracy of the other tool used for “its” accuracy. But, love it as a two pack as we have two vehicles with a max psi of 45 & 55 respectively. I was told it’s best to get a personal tire pressure gage, that has a narrow range that fits your needs, (for a more accurate reading of “your” vehicle) as opposed to one that has a wider range psi, reading up to the hundreds, which provides a less accurate reading. An example of this is at gas pumps, they’ll use a built-in tire pressure gage on their air pumps that have a high psi range. Those have always given me an inaccurate psi reading for my personal vehicles compared to the lower psi tools that I’ve carried in my car/suv to avoid over/under pressurized tires. The bigger the psi range, the less accuracy it’ll provide. From my experience anyway.

It's accurate, looks good, works as expected.

I bought a set of two AstroAI Pencil Tire Pressure Gauge (10-75PSI). I tested both of them on three different cars we have at home with the following results: 1- They both read the exact same value, consistently. So they are precise. 2- Two cars are calibrated to 32psi and both pressure gauges read 32psi consistently on both cars. One car runs at 40psi, and in that case the gauges read correctly also. So they are accurate to within +/- 1 psi (maybe 2psi) in the range I'm interested in. Note that I'm relying on the fact that the pump at the gas station where I calibrated the tires, is accurate. However since they all readings agree with each other, chances are they are accurate. 3- They look OK. It looks like they might be plated, so durability might not be as good as a stainless steel professional gauge.

These tire inflation gauges are fantastic !!!!! Very high Quality.

I purchased these a few months ago and I am so glad that I did. They are wonderful. Solid metal and very high quality for sure. They are accurate and very dependable and so simple to use. I highly recommend these to be carried in everyone's vehicles and kept handy in the garage or shop.

"Great onboard tool!"

Purchased for all of our cars,and one for the garage. Nowadays,we have Tire Pressure Sensor Monitors in all our tires.The "TPSM's" are built-in the tires.The TPSM's have batteries which eventually die.When one gets a yellow tire/dash-light,meaning low pressure on a tire,we can check tire pressure immediately.The TPSM's can point towards a low pressure tire(s),due to nail,screw,metal object.Or,in our case the 10 year batteries were D.O.A.

Great Value

I bought these tire pressure pencils because my old one of 5 years finally broke. I spent some time looking for non digital tire pressure pencils and stumbled across this one. They feel very strong and easy to read. I like how they are metal unlike many other ones that use hard plastic. I recommend this product for anyone who is look for simple tire pressure gauge.

Good accuracy and repeatability

The two pack agrees perfectly with each other and also with my expensive digital gauge. Money well spent. I'd like to keep a digital gauge in the car but the battery would die in the AZ heat, so I'm glad to have a good old analog pencil gauge for the glove box.

For the price these are pretty good

My dashboard readout was 37 PSI, all 5 of these read 38 PSI, so they are reasonably accurate. Not sure which reading is correct, the vehicle could be slightly off as well? At any rate I also purchased 4 digital gauges and they all read 36.5 PSI, or low by 0.5 PSI. For setting my tire pressure within spec's these will be fine, on my truck a pound or two, either way, doesn't appear to affect the ride quality or noise level.
