Based on Project Farm's Comparison Chart, ETENWOLF has the lowest total deviation for measuring 16 psi and the 2nd lowest for measuring 40 psi. Also ETENWOLF has a better seal rating than AstroAI. However, Project Farm reviewed an old version of the ETENWOLF that had a calibration certificate and the new version does not have one. However, Project Farm reviewed the AstroAI that uses a coin battery.
Have T300. Accurate to 0.1 psi up to 150 psi ( tested at 45 F and 100 F ambient vs. Fluke 2700G with 0.02% accuracy full scale). Accuracy increases above 1 psi below 32 F.
I will buy it because it has AI.

what is the use for these when most cars have tpm sensors? these moire accurate
A lot of cars don't have TPM these days....Including my 2021 Volvo XC90. The vehicle calculates differences in rotational speed to determine if a tire is losing air. Completely useless since it does not tell you the pressure. So, I need a pressure gauge. The system also depends on the user inflating the tires and then telling the car that the tires are properly inflated so it can monitor any changes. It avoids the battery in TPM sensors but causes a bunch of extra work for the vehicle owner.

How funny, I am getting it for my 2020 XC90 that is showing tire pressure warning. LOL

TPMS in most cars are like an idiot light. You have to set the TPMS and then It displays the warning once the tire pressure goes below a certain amount. Also (in most cars,) doesn't indicate which tire(s) are low. So, a pressure gage is needed. After any adjustment to tire pressure, set the TPMS. Some cars auto-set the TPMS after traveling a certain amount of miles. Vehicle user manual will enlighten you on that!

Thanks, OP. I needed a small add-on to get free shipping on Amazon and it's nice to actually get something I need.

Anyone find a version of these inexpensive tire pressure gauges that do NOT require an adapter to check presta or schraeder valves? Dealing with adapters is annoying.

Put an adapter on each presta tube. A tire gauge is designed for maximum accuracy. No clamping mechanism.

Federal Motor Vehicle Safety Standard (FMVSS) No. 138 only requires a warning if a tire is 25% below the mfr's recommended cold inflation pressure. That's approximately 8 psi drop for most cars. For a car that tracks true, a drop of 5 psi at one tire will cause the car to pull to the right or left at +30 mph.

I've had two punctures in 45 years. Drove home and repaired with a plug. I've seen people driving around with a flat tire for several weeks. They added air every few days.

Envious. You have a lot of toys! Good for you.
Pardon my ignorance, what is a "side by side"?

Not sure how good Volvos are these days, seem dodgy to me now, new owners are not the best for quality would be my guess
