Used on my car for the first time last night. Pros: 1] Very easy to use. 2] USB charger (Type C :-) ) so you can charge in advance and not be tied to the cigarette lighter. 3] "Set and forget" operation (the set limit unit will be deactivated once it reaches the set value. 4-5] Lightweight and portable :-) 6] The display is nice and big and shows the current psi, when you connect the valve so it can act as a test to see how well your tires are inflated. 7] just looks cool. Disadvantages: 1] The tube is too short. If your valve was at its highest point off the ground when you stopped blowing air, good luck. The cord is not long enough to keep the device on the floor, so I had to hold the device while using it. :-(2) Slow pump time. It took about 4-5 minutes to inflate a tire to about 5psi, which was slower than I'm used to, but it's not terrible. It's a small device, so the power limitation is understandable. Overall - definitely serves the purpose, would recommend.
