Ralthy Digital Tire Inflator with Pressure Gauge, 200PSI Heavy Duty Air Chuck and Compressor Accessories with Rubber Hose and Quick Connect Plug for Auto, Truck, Bike, Motorcycle, Backlit 0.1 Accuracy

First of all, it is digital instead of mechanical gauge which may be strong but not always. This one comes with rubber protection around gauge and light to assist reading at dark area. The connector to attach tire is well built and very easy to stay without hand. I also like the idea of continuous pressure reading and using LSD rechargeable batteries. The best thing is accurate. It also has two kind of quick connectors.I did find I can't calibrate the gauge and is not waterproof too(there is a small hole on the back of digital gauge, but there is nothing wrong so far.

This is the best tire gauge I ever owned, well built, easy to use and can be used for deflating as well as inflating (with a compressor). So why only a 4 star rating? The gauge is rated 5 star, however, the instructions (if you want to call it that) only 2 stars. It reminds me of the Japanese camera manuals of the 1960s. The attachments that come with it are not listed, you have to go to the Amazon web site to see them. Some of the errors: instead of AA batteries it says 7-cell batteries,damage pressure is listed as over 250PSI in one place and up to 300PSI at an other. The inflating valve is not labeled (it can also be used for deflating with no compressor attached. What is a "Quickly inflate chuck"? The digital display says battery and not battery status, the inflating hose is called tube and also pipe, the dial is stated as maximum diameter of 65 mm, why maximum?, reading accuracy instead of measurement accuracy, what is an "optional suitable universal connection"?, the On/OFF switch is "ON or Off, "Adopt eco-friendly material?. There are also numerous spelling and grammatical errors. The name or product designation is not on the sheet, presumably because it is sold under other names.

I’m probably on my 5th tire gauge in the past few years and I got tired of buying a new gauge every year. I’ve tried the good old stick tire pressure gauges to the electronic gauge and all of them have broken. Either they get gooey and stuck like the stick gauges or falls apart like the gauge emergency glass breaking tool. This one feels like a professional model that has some weight to it. It comes with a bunch of adapters that I will never use along with two batteries. Yes, it comes with batteries. I have an older SUV and drive over bumpy roads so I always have to check my tire pressure. It may be a bit t daunting at first, but all you do is clip it onto the stem. It seems to be very accurate and is tough as nails. I already have dropped it twice and it didn’t break. This could very well be the last tire gauge I will ever need to buy. Great product!

So I received the gauge and installed the fitting for the airhose and batteries. The gauge lights up blue in color and can be read very well. Unfortunately, the pictures shown in the listing and how the item operates is not exactly the same. You CONNOT see the pressure level of the tire while filling or draining air. The pressure reading changes and requires a second or two to stabilize when you release the buttons. The picture in the listing shows a direct reading of the tire pressure whether you're filling or draining air. This is not so. The listing also says the the gauge is accurate to .1 psi yet the guage displays in .5 psi . What is the point of being .1 accurate when you can't see it? Other than that, the guage seems pretty sturdy and offer convenience when filling air in anything. Ymmv, but it just seemed important to note the discrepancies as it may reflect the company selling the product. Will update if anything changes.

This item is made from some composite metal that is very weak. Right out of the box while screwing in the male adapter the casing cracked without hardly any stress on it. I did not even get to use the item. For something that is going to be used in a shop setting. Even in a home shop. The item needs to be manufatured with steel. Very disapointed. If you dropped this, it surely would break. I would not have this in my garage.

I purchased this tire gauge as a single woman who likes to keep my car in beautiful shape, but I have been known to neglect checking tire pressure as I used to go to a local gas station to use their gauge and air. This gauge is easy to use. The light makes it perfect for my older eyes, and I can check my tire pressure weekly when I drive into my garage. It’s right there; no excuse not to check. I still need to take the car to the service station if I need to add air, but this beautiful and sturdy gauge makes me check more frequently. I checked the air pressure with this gauge and afterwards took my car to the service station to check the accuracy of this gauge, and it was spot on. I’m glad I purchased this. I have an older car in mint condition, and this is another convenience that keeps my car safe to drive and gives me the best gas mileage possible. I would recommend this tire gauge. So much better than the old pen style, and the price was right.

I use this to inflate my inflatable boat, where low PSI readings are critical (under four psi). Most gauges at this range only show full psi, not partial or intermediate readings. I also like the fact you can easily change it from psi to kpa, which is a more common measurement for inflatable boats.I have used a half-dozen times, and firmness of the boat seems to be spot on with the readings. I've also compared it to a few other gauges I have, and again seems to be spot on.The gauge itself is very easy to read, and shuts off after a reasonable amount of time. Release valve to fine-tune is very nice as well. I'm sure I will use this on automobile tires in the future. Overall very happy with this, and recommend.

I bought this to use on my Porsche. The cars needs accurate fill or it screws-up the handling. It rated 31 pounds but showed 34 pounds with 3 other gauges. I bought this because the Harbor Freight one is junk. This is way better than the Harbor Freight item, but I will still check with a hand held gauge. Do a Google search on the best digital tire gauges and go with one of them. This is handy to fill and release air for an approximate rating, but then fine tune with a real gauge.
