Super heavy gauge, nothing compared to the heads of various foot - and are Standluftpumpen from discount or hardware store tuned! You pay Although firstonce as much as for a complete pump from the discounters, but what use is the current cost savings if the airline pump one year later flies in the garbage, because the head defective - or the tube is porous! I part with the provided one of my two defective hardware store pumps, now it works better than before! The head holds bombproof on the valve and also the take them from the head is no longer next to it, as the head lacks only air when the Schrader valve is already closed. When hardware store head had to be careful that you quickly withdrawing it after unlocking the valve, otherwise the laboriously inflated air flowed freely into the open air. Top!
