Weak but excellent please read.
Size: 50ft, Color: Black
Breaks a lot, but Is 100% convenient. My third annual purchase. Beats rubbing stuff off of twisted rubber hoses. Darned if u do. Darned if u don't. A 5-10 yr version one of these will outsell the entire market.

Style: 6 PACK, Pattern Name: Standard MERV 8, Style: 6 PACK, Pattern Name: Standard MERV 8
Looks like good quality. Only issues are they are not individually wrapped and the markings are confusing as one side says merv 8 one side says merv 11 and one side says merv 13
