The pump is in use for a few months and always travels in a backpack with - as always with such accessory items need some hakelige suspension and I therefore do not use - luck has been but rarely used to. The robust plastic material seems very stable, over the durability of the inner life, I can tell so far nothing negative - at the low use I hope it stays that way. With the cap on the pump head and the rubber lip on the pump handle, the inside is reliably protected against Schmuz. There are all the usual valve types are supported, which I use only Sclaverand and can confirm that the pump so that works well. . Inflation of especially large volume tire is facilitated by the switchable telescopic mode, whereby such pumps of course can never compare Floor Pump - nice to have for emergencies on the road, thereby the pump but also a few grams heavier. For this purpose the telescopic operation rattles very strong, which does not prevent the need arises from the use, but still a bit annoying.
Overall, therefore, a (so far) solid mini pump that served its purpose, nothing more, nothing less.
