Gauge arrived on time and in a very nice box with clear instructions. Checked gauge reading against what the car reads and it was less but within one pound. I think the car rounds up as it only shows whole numbers. Easy to read and seems durable. I would really like to keep it in the car, but they recommend not keeping it in temperatures above 95 degrees, probably because of the batteries, which keeps it out of the car in summer here in Florida. Speaking of batteries, this one take two AAA batteries and not the expensive flat batteries which is great. Only had it for a short time, but so far so good.

The gauge seems to be of a high quality. The packaging is something that you would expect to see with a high-end Samsung or Apple smartphone. The gauge is quick to read and display the tire pressure. Not too bulky/heavy, which will be nice if I decide to carry it in my backpack when going out riding. Bonus points to the manufacturer/seller for including the 2 AA batteries that are needed for the Product. I feel like I purchased a high-end tire pressure gauge. Even Samsung and Apple don’t include chargers with their thousand+ dollar phones.
All of that being said, I was slightly disappointed when I realized that the Presta Valve adapter was to be put on the valve stem itself and not on the gauge. I have a handful of bicycles that have Presta valves and I thought that the adapter included was to be put on the gauge – not the valve stem on the bicycle. I am not going to knock any points off on the product for this. That was my misunderstanding of the design of the product. I still recommend this product, but I wish that the description of the product was more clear about the Presta valve adapter. But, at this price point (purchased when on sale for $8 – wow, what a deal!), I have absolutely no complaints. I could buy a set of adapters to put on my bikes and that would solve the problem, but I was hoping to avoid that and still be able to quickly and easily check pressures for tires that have Presta valve stems.
Overall, I am pleased with my purchase. If you need a quality tire pressure gauge that isn’t too heavy and provides a digital readout in a second or two, I don’t believe that you could go wrong with this product. Just be aware that if you were hoping for the Presta valve adapter to be a part of the gauge so that you could just put the gauge to the valve stem and check the pressure, this gauge is not designed that way. You must put the adapter on the Presta valve stem itself and then check the pressure.
I would recommend this gauge to friends and family.

Okay, hands down one of the best digital tire gauge in terms of build quality, ergonomics, and using triple A batteries. No other digital gauge uses ordinary batteries. When my AccuTire gauge finally gave out a year after purchase, finding the button cell batteries for it at my local Walmart was a pain.
Measuring the tires on my car, it gave accurate reading and doesn’t leak air while taking measurements. The good news is that it resets after each measurement without having to turning off and on the device. As long as I’m moving to the next tire and performing the next measurement before the 30 seconds elapse, I can do all four within a couple minutes.
A couple of downsides is I cannot adjust air on my tires like other digital gauge by simply pressing the pin in the center to let out air. Another is the display. If I’m measuring in full sunlight, display is a bit hard to look at unless I cover it to read the display. Both of these do not warrant a drop in rating as it’s more for build quality and ease of use.

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!
