This us small light and the led was great. But when i used it it was impossible to get a seal and a lit of air was released. So unable to get a reading

Doesn’t work very well at all. Attached valve and let more air out than any other gauge I’ve ever used… very poor quality and not really fit for purpose.

For less than a tenner it’s a ‘must have’. In the family we have 3 cars and motorcycle. Using this in combination with a bicycle pump (go quality but not most accurate gauge) it’s literally a 5 minute job to check and add air to each car when required.

The measurement seems to be fairly accurate and repeatable - good enough for your average vehicle tyres anyway. Certainly much better than the old pop out metal sticks I've been using until now.Unfortunately, getting a reading is not entirely easy, as you have to wiggle it a bit to get a good fit, and usually loose a little bit if air in the process. I took it apart and was disappointed to see that the entire receiver where you insert the valve is made of cheap plastic, including the important centre pin that pushes down on the valve's central pin to open it while taking a reading. This centre pin is already looking in a bit of a sorry state, and I've only taken one set of car tyre readings with it (and I was fairly careful!), so I have doubts it's going to last very long. If this pin had been metal, then I might have been happy with it overall, given the price.

I have written a little about Astro AI digital tyre pressure gauge but want add a little more about it. One car has runflat ultra high performance tyre which needs different air pressure on front and back, for performance cars you need to have accurate pressure and this gauge made my life easy.I have checked the gauge in comparison with the manual and digital gauges; it gives the accurate results and that’s what you want. Very easy to use and handy to keep always in the glove box⭐️⭐️⭐️⭐️⭐️

Nifty gadget at excellent price. Easy to use and accurate. Incorporated torch a nice touch. Pretty sure batteries will last a long time as a pressure gauge is not a tool that is normally used on a daily basis - unless one is a mechanic, or similar occupation. Nice one. Thanks.

This provides a good general indication of tyre pressure .. I have only marked this down as it can be a little tricky to get straight onto the value to get the reading .. if you don’t get it square onto the valve you can find you are simply releasing air from the valve rather than reading the pressure .. to get the best result I place 2 hands on the device to make sure that one hand holds the device and the other one makes sure you get it straight onto the valve .. it can give a slightly different reading to when I use the AstroAI tyre compressor .. so sometimes I don’t use this and put the compressor straight onto the valve to check pressure and inflat in the one process .. This is great just to get a general indication whether a tyre is loosing pressure

I used gauge to measure the tyre pressure in my Micra. It was showing PSI of 28. But then when I used an off-the-shelf tyre inflator to inflate the tyre to my surprise it showed exisitng PSI as 31 before inflating. And ithis happened to all 4 tyres. I highly doubt if the AstroAI reading is accurate enough to trust.Correction: The seller sent me a replacement pressure gauge and the replacement one far more accurate. SO I have now changed the rating to a three star..

Looked good when I got it just about three weeks ago, light was a good feature, went to use it today for first time and batteries for light and pressure reading were dead so absolutely useless, had batteries for light but will now need to buy new button one for reading gauge, hope it’ll work after that.

This pressure gauge is very easy to use, much easier than the others I have owned.I found it very accurate and it stays switched on long enough for me to go from wheel to wheel.Also, unlike some others, it is possible to change the battery.Very satisfied.
