We have had this tire inflator for probably close to 10 years. - 4 cars later and it's just as efficient and reliable as day 1. We have used it time and time again and never had a problem with blowing fuses or failure to inflate. I cannot say anything negative about this product. I'm thinking about buying a second one in the unlikely event that this one dies on me. It feel very confident knowing my son has this inflator in his car. Definitely worth your money!!
...and the reason it does is because it draws 15 amps of electricity. Thus if your socket is rated 10 amps, you're cooked. Meaning a blown fuse. No thanks
I like this item, and we own multiples. What I do not like is that, without fresh batteries, the "auto off" feature does not work. Be sure to go to a dollar store, stock up on button cell batteries, and keep them handy. Though the car powers the device, the detachable pressure-checker is useless without them.
Luckily I got this thing for about half price because paying over $20 would be a shame. It works okay for inflating but is pretty slow... The removable gauge has a very weak contact point with the inflator so putting it back on can be difficult without bending the thin, fragile connection teeth. I only got to take it off about twice and it quit working and can't preset the pressure any more. I just have to keep disconnecting it to check the pressure with another gauge. They really shouldn't have made the gauge removable because this would have been a great product otherwise.
