Very satified with the item. Highy recommend. One note only - to manufacturer - it could have an air valve (the same as air valve for the tire). I need to redo it myself before to put it in use. Good quality at a good price.
From order to delivery by my local postal service around 25 days. Well packed in foam and foil. Pneumatic drum not tested yet with dedicaded grinder but same drum looks really good. After pumping, pressure is on constant level. One thing which I want to change is valve from Dunlop to Shrader. Dunlop works ok but Shrader is more polular.
