Query: These rock

They do want they say they do, but if you haven’t cleaned the duct vent in 25 years you could possibly get all 8 rods threw but only got 6 rods out lol was so jam packed with lint it got stuck right at a 45 that was a pinch point so ended up cutting a hole in the drywall and just replaced section of ducting. Very easy to use
