Product review (5 stars): Shafts are super flexible. Works easily with drill
Phenomenal product. Shafts are super flexible. Works easily with drill.  Great to write a five star review for once. I may start moonlighting it was so easy and effective. Simple sell.

Read the manual!!!!  Very good tips on how to use it and access the lovers from outside. Run dryer on blow without heat and go from outside worked great.

Don't forget drill attachment accessory. This will prevent crushing the female threaded end.
I hauled out 5 gallons of lint from a 36 ft.  pipe run. 11 years of a family of 4 and various pets along the way I guess.
