After an exchange of first inflator is breathless in 30 seconds of use, not better with his replacement! 10 minutes of continuous use (max advocated by the manufacturer) and less than 200g and more in the tire with the arrival royally 1.9 kg (checked with a real manometer) For sensee pump go to 18 kg of pressure, the least we can say is that it's not swell! What we would not do to swallow French with Germany and more quality "tested and inspected by Einhell" I invent nothing, it's brand on it. For once, I miss no air!
In short, to avoid to cover yourself with ridicule on the roadside, product away if you have an ounce of quality requirement and if you do not like unnecessary gadgets scam trend!
