The device itself is perfect for mounting under the seat in my car. It's a 12v only plug which I didn't like a bit - my car has both a standard and 12v socket. It's a flip lock (ignore the statement in my so unprofessional video, I have both and I've just tested them against others for comparison) It inflates quickly with near perfect accuracy (I have a psi gauge to compare used). You can set the psi and the device will automatically turn off when it's reached - this was a big +++POSITIVE for me as I didn't have to constantly check the psi. I liked the extra attachments as the kids always have to use the bike or ball pump. It will automatically turn off if PSI is not reached for a period of time to prevent overheating
