I have just received a Cyclaire Plus pump. What a heap of cr8p! It does not work at all. After finally working out the totally unclear instructions we have and being stupid enough to believe that it works on EVERY type of valve which is total lies, it has not pumped my Batavus or my husband's presta valves. The dial is simply not working at all. My husband is able to put more air into his tyres using an old-fashioned pump with a nozzle that the treads are worn on. How this piece of utterly useless rubbish has ever won an award is unfathomable. I am packing it up and sending it back.
