Accutire Digital Tire Pressure Gauge (5-150 psi) psi/bar/kPa/kg-cm2 (Black) | Backlit LCD Display, +/-0.5 psi Accuracy, Auto Shut-Off, Rubber Ergonomic Grip, 4 Valve Caps, Batteries Included, MS-4021B

Easy to use and very accurate.

Great product. Easy to use, easy to read. Finally, a tire pressure gauge that I can like.

Surprisingly easy to use and accurate. Certainly far superior to a mechanical gauge.

No complaints here, seems to be good quality! Material is a bit cheap but for the price it's too new expected, but already it works well

My old gauge finally failed, and I bought this one because of its ease of use and reported accuracy.

This works great! Easy to use.

Tire pressure gauges are about as unsexy a product as you can think of, but this one comes across as a top-notch example of industrial design. Its appearance is just as attractive when it’s in your hand as it is in its Amazon page photos. And in the best form-follows-function Bauhaus tradition, it invites you to hold it in a way that makes testing your tire pressures a simple, one-touch operation. Unlike some mechanical gauges I’ve had in the past, it’s easy to get a reliable reading with this digital gauge on the first try. Simply remove your tire’s valve cover, push the gauge's start button, then firmly press the sensor straight ahead onto the valve. (Don’t come at it from an angle.) In a fraction of a second it will get a reading and not let additional air escape. That reading will be to the nearest tenth of a pound. I believe its accuracy is to two tenths, and that’s plenty accurate enough. Going digital is such a nice change from mechanical sensors, which from my experience anyway would start the valve hissing with escaped air when trying to get a solid fit, and then hiss some more when removing the sensor. And mechanical gauges, even the fancy brass one I used to own, are notoriously unreliable. This little beauty is featherweight and doesn’t get dirty when you check your tire pressures, so it can live in your glove compartment. If you forget to turn it off, it will turn itself off after 15 seconds. The battery should last a year. And for the quality you get, the price is a bargain. If over time my experience with this product causes me to re-evaluate it, I’ll update this review. But so far so good! And one more tip: Go to Big O or another tire specialist and pay the $10 or so they charge to fill your tires to their recommended pressures (see the sticker inside the driver's door) using nitrogen gas. Unlike regular air, which tends to “bleed” from the tire over time, the nitrogen will stay put. Racing teams have known this for years and always use nitrogen. And now it’s available to you and me. My nitrogen filled tires have gone a year without losing more than a pound of pressure!

Tire pressure gauges can run from the simple pencil types to the more sophisticated versions with dial or digital displays. Picking a good one depends on your personal needs, more than anything. Bought this Accutire MS-4021B Digital Tire Pressure Gauge when it was on a Lightning Deal and based on personal experience with an older model from the same company. My needs were specific: measuring the tire pressure on a mountain bike. This review wouldn't even be here had I not lost the original gauge by leaving it in my back pocket when going out on a quick ride that became extended. ◆ Likes: + Clear LCD display; easy to read in varying conditions + Good tire pressure range; from 5-150psi in ½-pound increments + Well designed; angled head makes it easy to use + Uses three LR44/A76 batteries; readily available ◆ Dislikes: - The three LR44/A76 button cell batteries are tricky to replace ◆ In Use: This digital tire pressure gauge is quite straightforward, and the directions for use and warranty info are printed on the back of the package. Before using it for the first time, it's necessary to pull out the small white paper tab from the rear of the handle and it will work just fine. To use the gauge, simply push the nozzle onto the tire valve stem and press down smoothly so that you don't hear air hissing, then hold it there until you see the pressure reading lock in on the digital display. The directions also include directions for checking the "zero setting," so be sure to remove the cardboard portion and keep it for future reference. My MTB tires are 26 x 1.95-inch, and on the sidewall the pressure range is noted as 30-65psi. I changed the air pressure a few times to see how well the gauge would respond, and it worked properly. I then checked it against my Planet Bike Analog Bicycle Dial Tire Gauge , which is very accurate and rated at 0-140psi, and the one that is used in the field. The two were very close, though the Accutire MS-4021B is a bit handier to use at a glance due to its digital readout. My only issue with this Accutire gauge is that the three button cell batteries are tricky to remove and replace. You'll need a small Philips jewelers screwdriver to remove the battery cover on the black handle, and you'll need to use care in prying out the small batteries or they will go flying... as happened to me the first time. When I reinserted the batteries, I cut a small, very thin piece of plastic and slipped it underneath the batteries so that they could be removed easier the next time. A small piece of tape would do just as well, but it a small nuisance. ◆ Summary: The Accutire MS-4021B Digital Tire Pressure Gauge is a decent product, and one that is easy to use. Bottom line is that it's a good multipurpose digital tire pressure gauge. 7/30/2013

El general facil de usar solo es preionar un boton y el chequeo. Llevo unos meses con el la pila sigue igual funcionando y se ve de buen calidad a precio accesible.

This little Digital Tire Pressure gauge is fantastic! It is dead accurate, super easy to use, and read on the fly. It makes keeping my tires and my partner's tires where they need to be super easy and practical. This is far better than the old manual tire gauges that I grew up with.

This fortunately reads psi. It reads the same as another gauge I have and agrees with the car's TPMS so all three must be correct. I have an old version of this gauge from probably 20 years ago and it still works on the original battery. It's very easy to use and is highly recommended.

Accurate as expected

Excelente producto. Se ve claro, es preciso. Solamente a veces la valvulares negra como que si se afloja y se debe de apretar antes de medir. Para que la medición sea correcta se debe de medir en frio. Entonces carga las llantas a 6 psi más de lo que indica el manual. De ahí ya lo dejas la noche y en la mañana antes de partir lo dejas. Manejar con las llantas bajas causa el mayor desgaste y que exploten en carretera.
