I ordered two 1/2 shank nozzles, they sent 3 nozzles none of which matched the type I ordered and they were all 1/2 shank four . Also, they sent two small aluminum corners thrown in the bag. It was a manufacturer or seller, made in China in a sealed package. The packaging was labeled with the correct two bits, even 1/2 shank is printed on it, so I waited until night before I had to take it to work, I worked to open it and realized I had the wrong aftertaste would have. aggravating . Now I will soon receive a new order (another seller) in 3 days. Thank you friends. Thank you CHAMPIONSHIPS. master
