Drives at 5 bar until at least 4 times on pumps very satisfied remains a luxury but happy with it. Slightly larger than a car key
Been working with cartridges for years but was particularly looking for a digital reading method of tyre pressure. Ideal for travelling and weekend trips. A quick top-up is easy to do. And also to play with the tyre pressure on the road. The easiest way is to turn the valve all the way down and then pump, which makes it easier to read the display in combination with operating the pump button. When the preset pressure is reached, it stops automatically. Pressure can be customised by 0.1 bar per step.
