ETENWOLF T300 Plus Tire Pressure Gauge 200 PSI, Digital Tire Gauge with Bright LED Display, Tire Gauges for Tire Pressure with Presta Valve Adaptor (Space Grey)

This gauge is AMAZING! Consistent readings, solidly made, and for just $8?!?! Can’t be beat.

This is a very handy and, from what I have measured, accurate digital tire pressure gauge. The display is easy to use and you can cycle between BAR, PSI, KPA and the one button operation is nice. There is a light that will illuminate the area in front and this makes it easier to see in the low light situations that you will most likely be in when you need this. There is a presta valve attachment tucked inside as well that you can use for those bicycle applications. The inclusion of the AAA batteries and a cloth carrying case round out this easy to use digital tire pressure gauge.

I'm very happy with this T300 Plus tire pressure gauge from Etenwolf. It's comfortable to hold, has a simple one-button design, and uses a built-in LED that's bright enough to help illuminate your work area when you're kneeling by the car. The use of 2 AAA batteries helps keep this gauge powered for a long time versus more common coin cell tire pressure gauges. The alkaline batteries included are certainly fine, but I may swap them out with AAA lithium batteries at some point just to avoid any chance of alkaline battery leaks.This gauge is fine with my car's tires, which are in the 20-35 psi range, but the gauge reports being able to read up to 200 psi, covering high pressure road bike tires. I can attest to it doing a great job of getting repeated measurements off the same 25 psi car tire that only vary by 0.1 psi. The readings show up when you press the gauge onto the tire stem and it makes a stable seal. The readings can be cleared with a momentary tap of the trigger button too. If you want to turn off the gauge rather than wait for it to automatically sleep, holding the button for 3 seconds does that.I looked very carefully at the battery compartment while installing the batteries. The symbols + and - are printed in the plastic that's visible on the top and bottom with the battery compartment open. The battery compartment's clips are designed with a slight offset that makes the battery compartment only close one way. There's also an included instruction card advising that the battery - terminal connects to the long spring and the + terminal to the short one. I would expect a pair of AAA batteries to last many years without needing to be changed but I'm glad there are markings on the casing so I don't have to rely on a tiny card.I didn't deduct for it, but the calibration card is designed with a font that imitates handwriting. It could just be printed that way and reflect actual testing, but it could also be mass produced and not reflect testing of the same tire pressure gauge in the box (which doesn't have any sort of individualized serial number visible).

This little gadget does its job and does it just fine from my observation. It tells you on a fairly easy to read LED display what your tire pressure is. It seems to be accurate and I didn't find much to be critical of except one thing. We'll get to that in a moment.I'm really happy this came with Duracell batteries! That's about the only reason it's getting a 4 star review from me, if I'm being honest. Duracell are the most reliable in my opinion (sorry bunny...it's simply the truth...).Now, to the critical moment. This thing comes with a carrying bag to store it in. The problem is there is NOT room for the gauge and its instruction booklet and other paperwork at the same time! I don't get that at all. If you're going to have a bag included with a gadget, it should accommodate everything needed for the gadget, including its instructions and other paperwork. That's my one gripe. This isn't a bad little gadget, it just needed all of the things that came with it to be a little bit more well thought out.

It's a fancy looking pressure gauge. Feels good in the hand with its smooth texture. LED screen is bright and big making it easy to read. It uses AAA batteries and comes with two Duracells not some generic brand so that was awesome to see. I like that it uses AAAs versus the button cell batteries you often see in some digital tire gauge. In the battery compartment there is also a Presta valve adapter which is another nice bonus. It's great if you have road bikes that often has Presta valve stems for the skinner tires. The little carrying bag for the gauge is also really nice and fits the gauge perfectly.It's difficult to test the accuracy of the tire gauge since I don't have a standard benchmark to compare it to. However, comparing this gauge to my TPMS reading and another digital tire pressure gauge for my second car, they read 32.6 psi, 32.4 psi, and 32.7 psi, respectively. Seems darn accurate to me! The tiny flashlight in the front is an awesome feature that really help at night... no need to fumble with your phone's flashlight.It nice looking. It works. It's accurate. If you're hesitant to get this, don't be. Just get it, but no "pressure" though... HA!

Sturdy feeling exterior. LED lights to help when used at night. Includes two AAA materies of decent quality. Battery door is a little awkward to open and close and there is no indication on the case as to battery polarity. So, you are left to guess how to put the batteries in correctly. I think that they realized their mistake as there is a small card in the instructions indicating the correct way, not too helpful for when you have to change the batteries in the future. They also touted accuracy but compared to a calibrated gauge that I have it indicated ~1.8 psi high.

This works great, comes with a hand written calibration sheet.Its small and comes with a pouch to keep it in and fits perfect in a glove compartment.I ended up with a nail in my tire so I am using it a lot, and am very happy.It comes with Duracell batteries which is a nice touch.
