Tiny Tire Pump 600 - Pro Power in a Pocket-Sized Pump

A bit bigger and heavier than I was expecting . I have tested it at home and it works the way it is supposed to. I set the pressure on two different types of tyre and checked with mu normal pump and the pressures were correct. I have not as yet had to use it in real puncture situation . There is one slightly worrying thing and that is the very small robber o ring in the connector , it would be very easy to lose this and then be unable to use the pump effectively if at all

Excellent pump

Pump works really good, makes checking tyre pressures so fast and easy, only fault, you have to watch you don’t lose little o ring on the fitting which pumps up mtb tyres, it sometimes comes out when you are taking it off the valve.

Hot air

I Have a presta valve and I noticed that a o-ring is necessary on the valve in order to crew/seal the connection between valve and pump.
