Very easy to use. Consistently reads the same PSI as Discount Tires inflate/gauge station available for customers to check their tires. The manager says their station is accurately calibrated. This Etenwolf does not leak air when checking PSI, illuminates the valve when it is powered on, and the LED screen is very easy to read whether it's dark or light outside. Using AAA batteries is great. My only suggestion would be a nub at the bottom of the gauge for letting some air out when needed. I drilled a 1/16" hole in the bottom of the handle and inserted a very small screw leaving the head of the screw slightly raised. Works great for deflating. The screw does not affect the battery compartment in any way. I highly recommend this affordable, accurate and easy to use tire pressure gauge.

Great gauge. Accurate and uses two "AAA" batteries for a long life. It has an LED light on it which makes it great to use in low light. Very easy to operate too. Very nicely constructed. Best gauge for the money on Amazon.

Tired of old school tire gauges that gave me inconsistent readings, I opted for a digital one. This one is easy to use and gives consistent and accurate readings every time so far. I keep it in my glove box. The one thing I didn't like about it was that it times out too quickly when airing up all my tires. I kept having to turn it back on to check readings. It's probably to save battery power, but it was mildly annoying. That said, its a great digital alternative to the old stick type of gauges and I liked it so much I recommended it to a lot of people.

When the last of my digital tire pressure gauges, which are no longer manufactured, recently stopped functioning, I began research to find suitable replacements.There are of course many digital tire pressure gauges from which to choose, however the vast majority of them failed to impress for a variety of reasons, not the least of which were their poor or mediocre specifications or numerous user complaints.After a considerable amount of research, I located the Etenwolf T300 digital tire pressure gauges on Amazon. The most significant data which received my attention is that the Etenwolf T300 gauges conform to ANSI/ASME Standard 40.7 2A. I had not previously encountered affordable, consumer grade gauges that were calibrated with that level of accuracy.ANSI Standard B40.7 level 2A is a standard which applies to digital process gauges, and specifies accuracy within a +/- 0.5% span of permissible error. That level of accuracy means that on a 35psi automobile tire, the expected accuracy of the gauge is within +/- 0.175psi which is a ridiculously high level of accuracy for inflating a typical automobile tire.However, that ANSI B40.7 2A claim appears to be an error on the webpage. According to the printed manual which accompanies the T300, and according to the individual Calibration Certificate included with the gauge, the T300 actually conforms to the far more stringent and more precise B40.7 Level 3A standard.B40.7 3A specifies accuracy within a span of +/- 0.25%. That is a level of accuracy that is needed for industrial test gauges.The other specifications provided in the product description included the usable range of 3 – 200 psi which makes the Etenwolf T300 suitable for almost any tire I can reasonably expect to use, including my low-pressure garden tractor tires.Another factor that I found very appealing is that the Etenwolf T300 is powered by 2 – AAA batteries. Many tire pressure gauges require button batteries of various sizes, which never seem to be immediately available to me when they require replacement. With the ubiquitous AAA batteries, I am assured that I will always have replacement batteries readily available when needed, and even when away from home, they can always be easily purchased in almost any local store. Etenwolf provides 2 Duracell alkaline AAA batteries with the T300. I have also used the gauges with Ni-MH rechargeable cells, and they perform perfectly well.I ordered a Cyan case T300 because Amazon had them available for more rapid delivery than the Orange model (there is also a Gray model, which was out of stock when I purchased).Once I received the T300 and evaluated it, I was very impressed.The plastic case appears to be a reasonably thick, and potentially durable gauge of injected plastic. The T300 has a very solid feel and heft, which impressed me. The assembly of the T300 appears to be very good and precise. This tire gauge genuinely appears to be of very high quality. The battery compartment at the end of the unit has a slide-out which also stores an included Presta valve adaptor for high-pressure bicycle tires.The white 4 place LED display digits appear to be 11mm tall x 5mm wide. The gauge resolves to 10th PSI (1 place right of the decimal). Most tire pressure gauges only resolve to ½ PSI display. There is a momentary, rocker type switch on the lower part of the case which controls all functions including power and unit of measure selection. The T300 can measure and display PSI, kPa and bar. Holding the switch for 6 seconds will turn the power off, but the gauge will also shut down automatically after 30 seconds of non-use. After a measurement, the gauge resets to 0 in approximately 5-6 seconds for repeat measurements. The digital display also displays low battery level once battery reserve falls to 20% or below.The nose of the gauge, which must mate with the tires Schrader valve, seals very tightly against the tire valve. There appears to be a compressible rubber gasket in the nose fitting, which ensures a solid, leak-free union with the tire valve. Resultantly, the T300 produces very quick and reliable measurements without the need for repeated repositioning efforts to get an adequate seal for a reliable measurement. There is a white LED lamp below the nose piece which makes use in dim or dark environments possible.I evaluated the functioning of the gauge by taking multiple (many) repeat measurements using both PSI and kPa scales. The repetitive consistency and accuracy of the readings was notable.I was so favorably impressed with the T300 that I ordered a second gauge (this time with the orange case).When I received the second T300 I could not resist comparing them. I collected more than 20 successive measurements, alternating the gauges. (Total of 44 measurements collected). Half of the measurements were obtained in PSI and the other half in kPa. The consistency and accuracy both with the same gauge, and between the gauges was extremely impressive.I believe that the Etenwolf T300 tire pressure gauge is outstanding. It is well constructed, giving rise to the belief that it will be very durable. It is extraordinarily accurate, being calibrated to a measurement standard which applies to industrial process gauges. It functions very well and with consistency. The Etenwolf T300 is the best tire pressure gauge that I have used, and I am hopeful that it will provide many years of reliable service. I would not have purchased two of them if I was not extremely impressed with them!

It took a little while to get to understand how this works, however it's quite simple and works really well. The unit takes 2 AAA batteries which are included and a user manual. It measures from 3 to 200psi which is great.....I love the fact that it has air lock which is a unique sealing design which minimizes air leakage and gives a very accurate reading when checking presure. Also has a nice led reading and light on the front for night use.

This pressure gauge worked as expected as was easy to use. It's small and light enough to keep in the glove box and works great in low light conditions with its built in light and clear display. Worth the small investment!

I purchased this and the Etenwolf tire inflator and both are great. The pressure gauge seems to be accurate and is consistent between readings which is important. The quality is excellent and the value is tremendous. Good Job Etenwolf.

As others have already mentioned, this feels like a medium to high-quality product. It neither looks nor feels cheap, *especially* at this price point.I’ve tested it multiple times, and the pieces slide smoothly, the texture feels nice and most importantly, the user data feedback from the gauge is simple, straightforward, and precise. It might not be the absolute best, but considering the price, it performs exceptionally well.I now keep it permanently in my bike saddlebag. I hope this helps you decide whether to spend your hard-earned cash on it or not.
