I've had this item for ~7.5 months.
Unfortunately, my tires/tubes require 120 PSI (~8.5 bar), so it's tough to top them up. Also unfortunate, is that this pump doesn't deliver. It promises 11 bar, which has the same truth in it as most politicians. It can definitely do those 120 PSI, but getting there is very, very hard.
However, the true reason for my 3 stars is that it's almost impossible to keep the Presta valves properly aligned with the pump's delivery mechanism. 95% of the times the pump starts pushing the sides of the valve, and more air is coming out than in. This happens after ~80 PSI, and prevents you from going higher. You have to take the pump bit out of the valve, and connect again, this time trying to align them perfectly. Perhaps it's my fault, but the pump I can borrow from a nearby store doesn't have the same problem.
Also, plastics. Too much plastic. Probably won't last long.
So, all in all, for 20€, it's not bad. It's not great either. It's just ok. Spend a bit more if you have high-pressure tires. Go with this one if you have "normal" tires (as you'd see in a Cityrad, Trekking, etc.)
