I've had a while to test this tire pump at this point. I have to say I am very pleased with its performance!
I set a baseline for the built-in tire pressure gauge to see how far off it was consistently. I compared the readings with a Longacre tire pressure gauge I ordered from Amazon. The built-in gauge consistently read about .5 psi higher than actual, which isn't too bad.
I also got a chance to test the "set it and forget it" feature. With this feature, you set the pressure you want your tires filled to, attach the hose, and let it rip. It will fill the tire to the specified pressure and then turn off. Because the built-in gauge reads high on its own, I set the pressure 1 psi higher than what I wanted the pressures to be since you can't adjust it in smaller than 1 psi increments. This was just fine, because I found that if I set it to something like 36 psi, it will fill to an actual 35 with just a hair above that. The amount of bleeding I'd have to do with my real pressure gauge was totally minimal, maybe a tap on the pressure release button and the job was done. The auto-fill feature of this gauge is quite excellent once you know what the differential is between the pressure it thinks and actual pressure.
Fill speed is very fast! This pump filled 3 psi (the most I was lower than desired) within seconds.
Overall, I am very satisfied with this pump and highly recommend it to others that are looking for a great space-saving, budget tire pump.
I'm gonna scoop one up because of the "BP approved" stamp.
