Query: Vacuum cleaner bags not Royal Dirt Devil !!!!

These bags are advertised as Dirt Devil with the name on the bag. THEY ARE NOT ROYAL DIRT DEVIL BAGS. They are reproduced by EnviroCare Technologies. The bag states that they are designed and developed in the USA, BUT in the end they are manufactured in China. Ripoff!!!!!!!!! It is only a guess so far if they will perform as they should.The only good thing is the ship time. I ordered on Monday and received them on Wednesday. Very Quick.
