A part of the review has been auto-translated.
The pump arrived in one piece and in good condition. the light on the side is handy, it can be switched separately. Practical design, convenient extra storage. only difficult is finding the on/off button. But once you find it, the display light up. Overall, the device is fine :)
Internal battery is charged by USB. It has a row of LEDs which can be turned to flashing mode for safety lights. The short tube screws both onto the car valve and into the pump. I set it to 34 PSI and it switched off automatically. The control buttons are flush with the body which gives it a clean appearance BUT at first, they are hard to figure out. At least you don't have to mess around with plugging into the cigarette light plug. So if your stupid slow leaky tyre needs a pump up now and then (just because I haven't got round to fixing it)...it works fine. So far, So good
