Very well made and work like a dream to fish down a water pipe to find where there is a closed valve under ground. I would recommend this for a number of uses.
I have never used it before, mostly fiberglass. I don’t know how long it will last, but the guys said it’s a useless thing. It's better to buy from Klein Tool and use. But for the money it sits well on the shelf.
As a cable tech I run my line through smurf tube everyday. Sometimes these tubes are jacked up, missing a string or the string breaks. This bad boy will glide through 99% of smurf tubes with minimal pushing.
