easy to use and seems accurate… Read notes…
Note: use button to release pressure between measurements. This has seemed accurate when used correctly. At first I didn’t realize I needed to release pressure with the button between measurements… AND before putting batteries in just in case there is a little pressure from a previous reading or altitude change. Once I understood to do that, it is easy to use and seems accurate. I really like the flexible hose and bleed button. It made it a lot easier to read and adjust pressure on my tires, especially the ones with awkwardly placed valve stems (like on my sprinter van). It is of course a lot bigger than my smaller stick-style, but in my case I much prefer it.

Just what I was needing. Nice dad gift.
I was excited to get this. I have always used those little cheap ones with the stick that shoots out. This is so much nicer. It’s backlit and I can’t tell you how many times I have struggled to read a gauge in the dark. It also has an air release valve near the gauge so you can adjust your pressure if you get a little to much. The other stem caps and parts are just a nice bonus but the gave is what I was after and I’m really happy with it. It doesn’t feel like cheap plastic and it fits nicely in the hand. Recommended. If anything changes I will be sure and edit this review.

Accurate, affordable AAA-powered pressure gauge
Great quality electric tire pressure gauge with included replacements stems/caps. It requires 2 AAA batteries (not included). Other, cheaper Etenwolf pressure gauge products have been featured in independent testing videos and have performed extremely well against far more expensive options, so I use this one with the confidence of knowing that it is from a company that prioritizes both performance (i.e. good calibration) and affordability. This style is similar to others on the market, but sold at a lower price point. It had correlated well with my TPMS sensors and analog gauges. Overall, it’s a great product.

Great Value
It’s the best gauge I’ve ever owned. A much better deal here (with prime) as it’s $27 on the manufacturers website!
My only dislike is the need to hold the bleeder to reset the gauge to 0.

It’s cool!
Great product! Some reviews mentioned that the monometer does not turn off. To turn off the monometer, you need to press the air release valve. After reducing the pressure in the measuring chamber to the otmospheric pressure, you can turn off the monometer with the power button.

Good product.
I’m very happy with the purchase it works great the numbers are big and clear, the reason i gave 4 stars is because website description said battery are included but i did not received any battery’s i had to go and buy it .
