So you've bought the 2 pack. These units will be off by a 1 or 2lbs but I've never had all 4 tires with the exact same pressure. So it doesn't really matter much. If you want super accurate, buy a more expensive unit.
A number of our family members use the AstroAl Tire Pressure Gauge. We have also given the tire gauge as Christmas gifts to other family members. We like the back-light LCD light and the firm grip. It is easy to use and comes in handy to make sure our tires are at the optimum pressure. We recommend.
I like this product because it stays in the on mode longer than others I own. The advantage being you don’t have to keep turning on to recheck the same tire. It seems to be accurate too.
Worked Great

Useful note:
In order to get a good seal, please put the tire's air nozzle up or off to the side. It's the best when the nozzle is around 6 or 7 o'clock position so that you can firmly press the guage straight down which means you have to crane your head a little bit for reading. Always remember the most important thing for you is to be able to press down straight & hard onto the tire's nozzle.
Package Included
2 x AstroAI Tire Gauge
Works well and gets a more accurite reading than a conventional air guage.
Easy to read
Backlit light and consistent accuracy, is best gauge I ever bought.
The AstroAl is easy to use and gives a correct reading. The digital display is easy to read. I keep it in the glove box of each car. It performed as described.
Works pretty well so far. Haven’t compared accuracy
