The first tape stretched and became unusable after 5 minutes. The second tape broke after 15 minutes of vacuuming. They show retail packaging but you get Chinese fakes. A Sanitaire/Eureka belt will typically last for several hours of vacuuming. 2. Belt broke before cleaning 1000 sqm. ft. These are OLD TAPES! Vacuum Fix also sold me a 12 pack with the same problems.
