I wanted high-quality brush heads for my "Braun Oral-B Sonic Complete" electric toothbrush. I purchased "1X4=4PCS GENUINE BRAUN ORAL-B SONIC TOOTHBRUSH HEADS BRAUN VITALITY SR18-4 3 2" (acution ID 141216317974, seller: wendybebs)". When they arrived, while the packaging was impressive and looked genuine, the actual product was terrible. Badly printed logo, bristles that were cut flat instead of the familiar zigzag patter, unpleasant feel, rattling of the head when in use due to poor fitting, etc
