KOOTANS 11FT Diameter 4mm Fiberglass Running Electrical Wire Cable Pulling Fish Tape, Electrical Extension Cord for Wire

Used this to run some ethernet cables between rooms to my coms box and they worked great. Nice selection of tips and collapses away for a small storage footprint. The bright yellow also makes it easy to see inside the wall.

So I have to run my cat6 7 feet down an insulated basement wall, that means between drywall and the plastic vapor barrier tight from the insulation behind. My electric tape was unthinkable. So I went for this gadget. I tried pushing it from the top, but the angle against the joist above the ceiling made it rip the vapor barrier and go behind the insulation, so I thought, bummer! On a whim I pushed it UP, where the flexible segments would be less stressed improving the angle of penetration... and pushed and pushed and stop... it hit something. I went to the hole above the ceiling and there it was. I never thought something so thin could go so straight up!I went to the other end to bring the cat6 on top of the tile ceiling and it saved me time by being able to go 4 tiles over at a time (with 4 segments, the other 6 were waiting in the wall).The only snag (literally) was that the cable got caught against a joist and top of wall and while pulling, one of the attachments with flimsy split ring (think autoshop key ring) totally got deformed. So I used a piece of wire looped around instead of the ring. It worked.At the wall I used a braided steel cable with a red plastic cone to pull the cat6 and went down the wall without a hitch!!!To bring the opposite end of the cat6 inside the house through a small hole, I just pushed the pole segment by segment with the wife watching behind a corner TV stand. The pole went up along the corner until it hit the ceiling and then I shook it and it arched nicely for her to catch it. Easy as pie!Except for that flimsy split ring, it was perfect. The only improvement I would recommend is to include a male to male threaded adapter. It's hard to keep track of female and male threads in the heat of the battle.All in all, very impressed.Too much detail, bit I was so happy. In the past I've had to open multiple holes with some damage to the vapor barriers inside insulated walls, and inside the house, moving furniture and what not.

works well in my application

They are good to have in your toolbox just in case, but these aren't great quality and I've had issues with the pieces unscrewing from themselves while going down a wall. I will be investing in a proper set but these don't hurt to have in your toolbox or to leave in your truck just in case because of how small the total packaging is.

It's one of my best tools, and I always carry it in my Milwaukee packout. I wish to have one more hook, because it's easy to be lost.
