MS-4021B Digital Tire Pressure Gauge with 4 Valve Caps, 5-150psi (psi, bar, kPa, kg/cm2)

I am completely satisfied with this product. I purchased based on a consumer magazine recommendation. It works great, creates a quick and easy seal on the tire's valve and reads accurately. It's a good value for the money.

Works great, easy to use, quality product.

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

Use it often. Nice display.

Does what it's suppose to do. I've own a couple of these for the past 15 years. Always accurate, I use it quite often (daily)for my motorcycles. It functions well .

It was rated as the most accurate digital tire pressure gauge and I have to agree. Easy to use and read. I’m just disappointed that they are so hard to find now because they’re no longer being manufactured.

Works as advertised. Really good price for the accuracy.

This gauge is made of plastic but seems sturdy. I like that I can put the digital gauge on the tire stem and it automatically turns on and takes the pressure measurement. It seems accurate when compared to my tire inflator device that is digital.

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 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 tyre pressure gauge. You need to align the nozzle property to ensure minimal air loss while checking pressure. Also, you need to press the on button often as the screen goes off in a few seconds. Takes a bit of time to get used to it. Definitely easier and more accurate than my older pen-like spring loaded gauge.

This is my second of these tire gauges I have owned. The first was a gift given to me in 2003 after I bought my first brand new car. It is still going strong today (2015), without even a battery change. It feels sturdy in the hand, seems very accurate, and has never let me down. I would give that version a 4 out of 5 because it has a screen like a calculator, very difficult to see in the dark. It is its only failing. Fast forward to today, and I have have a new version of this tire gauge for my wife, as we recently became a two car family. Right away I noticed that the fit and finish is not as good as my older model. The two halves of the case don't seem to meet up as cleanly, and there seems to be a little bit of give when you squeeze. Also, the black tip, which can unscrew from the main body doesn't fit nearly as well as the older model. This is very readily apparent, and not a case of me being overly fussy. I don't trust that I will get twelve plus years from this more modern version. For that, I would knock this product down to a 3 out of 5. But, this version can be read in the dark, which I think is a great advantage. The red numbers are kind of like the numbers on an alarm clock. Great feature! For that I am bumping it back up to a 4 out of 5, tentatively. Time will tell if this product was made to last like my original, or has been cheapened and is now a disposable item.

Muy buen producto, quede sorprendido con su funcionamiento en lo rápido y precioso que es, ademas de muy fácil uso.
