Bought this a couple of months ago as a "fetish" cycling piece of gear and paid a bit less that 100 GBP. It looks and feels great but usability is poor. Removing the presta chuck from the valve stem is very hard to the extent I am worried the valve will be damaged. The bleeder valve to release back pressure does work but instead of releasing back pressure it releases the air you have just pumped into your tyres. The base is small so pumping hard is neither easy nor smooth but in fairness this is supposed to be a small and portable floor pump. All in all, do yourself a favour and buy a Lezyne or Topeak pump for half the money and do not get suckered in like myself.

I bought this 3 weeks ago and it really does look great - but it really doesn't perform. The design is poor. You can only stand on one of the floor legs so stability is poor. The pump head fits on so tight I have damaged a valve. The pressure gauge does not correspond to my other Pump (Joe Blow). So this expensive treat is actually mere folly. Save yourself a few quid and go for a cheaper option. You won't look so cool but you'll be richer!
