AstroAI Digital Tyre Pressure Gauge, 150 PSI, Backlit LCD & Torch | Calibrated to ±1 PSI with 0.1 increments and 4 units; Schrader valve checker for cars, SUVs, motorcycles and spare tyres.

Great little pressure gauge. Small, compact and easy to use with a backlit display and choice of pressure units. I've had this for a couple of years and still in the original batteries. Feels like it's made of cheap plastic but so far has lasted well and always works and seems accurate compared to a couple of pumps. Kept in car passenger door bin for easy access and so I always know where it is. Would definitely recommend it if you are going to look after it, maybe not if you are going to throw it around and drop it on concrete all day.

This is a cheap prices and - TBH - cheap looking device.However, it has a good grip, a useful and effective back light and uses 'normal' batteries that most people have a supply of at home.Unlike button batteries that I never seem to have to hand when I need them!These were a little fiddly to use, but my wife soon got the hang of them 😁😁Small enough to leave in the glove box until you need themNo real idea how accurate they are. Only used them a couple of times. On both occasions I took car to garage soon after and used the air pressure pump there. Didn't seem wildly inaccurate on either occasion.A good buy for occasional or emergency use, especially with the current price reduction.

During the icy weather the built-in battery of the old gauge failed. As its battery could not be replaced I had to dispose of the gauge. I wanted its replacement to be capable of taking new batteries, so this was a desirable feature for me with the new gauge. The built-in battery of the previous gauge had lasted a very long time; it will be interesting to see how long the replaceable batteries last in the new gauge. It is easy to use and the light might be useful on a dark night. The display screen is easy to read. As I only ever measure my tyre pressures in psi I would prefer not to have the option of being able to select other pressure units but I recognise that having this facility makes the gauge more applicable in other countries where psi is not used. The handle of this gauge is slightly wider than its predecessor, which makes it comfortable to hold. I have never previously had a gauge that measures in units down to 0.1psi. This is interesting but is not essential to me as I had always previously been quite happy with units down to 0.5psi!. I have used the gauge only once so far but it worked just fine and it seems to have been a good buy.

This brief review supercedes the earlier comments below and relates to a replacement kindly provided by AstroAI.The new AstroAI tyre gauge is slightly different in having different batteries. More importantly it seals to the tyre valve reliably. The bright display is useful and the reading resolution of 0.1psi is very good.Original Review on Gauge with 2 AAA Batteries:The gauge looks like it should be ideal with its good resolution of pressure (0.1psi) and easily replaced batteries. The gauge is let down by difficulty getting it to seal quickly to the tyre valve. However carefully I try to make it contact it nearly always loses pressure by 1 to 2 psi. Quite frustrating for what is otherwise a good gauge.

Just as described. Accurate as compared with another gauge I have. During use it is very easy to change the unit of pressure as the button is just at the top of the grip. A very clear read out indeed. Opted for this version as it uses 2 x AAA cells which I've always got plenty of to hand. Went for brown as a few pounds cheaper than the other colours available, it's absolutely fine. Very prompt delivery too.

Easy to use and like light to help you see. Have only used it a few times and on button has popped off so has left a hole in its place, not well made but measurements are accurate

Would be okay if you only measure 1 car.Then accurate measurement is less of a thing.As soon as you have figured out the corresponding reading with the actual pressure inside tyre, you’re okay!In my case, I am not sure if this is a keeper.Love the format, build quality, legibility and the use of AAA batteries. Better than “button-cells”Edit 28/3/23I have decided to keep the pressure gauge.Readings are consistent.The gauge showed me that 1 tyre is consistently losing air.I would've never found out on a normal petrol-station as there it immediately starts to fill up the tyre to required level.Now I was able to tell the tyre fitter how much it lost over 3x 3 days and he only had to check valve and soap tyre/wheel to find out that wheel was leaking air.So regardless the inaccurate yet consistent reading, less is less and tells me that tyre loses air.

easy to use, light is useful, 4 different measuring units. only slightly downside is the delay after taking one measurement before you can do the next, I switch it off and back on to speed it up. Would buy again.

Super convenient pressure checkerVery simple to use and a helpful feature where there is a light at the nozzle that helps a lot during night timeAccurate reading too

En algo tan fundamental como los neumáticos llevar la presión indicada aumenta la seguridad y evita desgastes irregulares en las ruedas y este medidor cumple perfectamente este objetivo, es fácil de usar, y en mi opinión es bastante preciso. Lo compré xq la gasolinera me queda un poco lejos de casa y era muy complicado saber la presión de los neumáticos xq una vez q llegaba estaban calientes.
