Because the magnet is small, the shut valve of the nozzle root is hard to use. I think that the marking of the screw diameter (1/4 three places) of the air manifold may be given. There are various settings such as proper pressure and diameter of bamboo shoots, but it may be included in the price made by NOGA
It's the worst. Air leaks are intense and do not become usable. Adjusted with adhesive + air tape + vinyl tape, it was not improved, but I do not know whether to sell such products often. Perhaps the manufacturer has not inspected it at the time of shipment.
