Which I bought it for to get my Toyota Prius tire pressure of about 25psi which turns on the low tire warning light . - up to the recommended 33psi it worked like a charm. It is easy to connect to a 12V car socket and the tube is very easy to connect to the tires. It's a little slow though, taking around 3-4 minutes per tire, but it saves you from gas stops, quarters and hassle, a good compromise if you ask me. The onboard sensor is a bit inaccurate, around 2psi, not a big deal but something to consider, I would recommend using a separate tire pressure sensor. It comes with a variety of tips and adapters and should work in most situations. My only complaint is that it's cheap plastic everywhere, including the hose end, and the noise it makes when running suggests it won't last long. I hope I'm wrong. But for the price it's still a good buy
