Review on 🚰 Drainx Easy Twist Drain Auger - Flexible Plumbing Cable for Drainage Clog Cleaning, 50 FT, 3/8" Diameter - Includes Storage Bag and Protective Gloves by Amrozi Papi

As others have said, for the half inch I expected it to be a little harder and when I say a little I mean a lot. I've tried this guy on my dryer vent, nothing particularly hard, no hard obstacles, and yet it would snag on a lint pile or bend and keep flexing back because it's too flexible. Roll over and over again, not just once, until the bundles of wires are wide enough to block the vent. Maybe that's fine for a narrow tube, but the hype about 3" fans is a lie.
