“Bought for small and lightweight pump to carry on bike with Presta valves.
Pump / valve seal starts passing at a relatively low pressure.
Pump would get you moving again on a partially inflated tyre after a puncture repair but certainly can't build pressure to fully inflate a tyre through a Presta valve.”
“My bike tipped over when pumping the tyre up the first time using the pump. It snapped the pump. Not very robust, and I wouldn't want to be relying it at the roadside.”
