Crown Root Cutters are quite an aggressive rotational tool for cutting through more stubborn roots and will also clear fat and grease build up of the walls of drains and sewers.

A difficult product to rate, it does work and was tough enough, and successful, for the one-off housholder (amateur) job that I bought it for, but the design has some limitations.
The main body and extended rod coupler at the rear are too long to enable it to navigate anything other than very gentle bends in 4" clay pipe.
I found it would easily deal with roots in the straight pipe sections that I could access from either end but no way would it pass 30 degree bends and would jam fast very easily. I decided to err to caution and did not try to force the tool any further around the curved sections of pipe.
If I were designing a tool for this task I would have a much shorter body with the rod coupler mostly contained within the body, teeth on the leading edge only and with a reducing cone shape at the rear so that it would not catch on retraction.
For our problem it was useful and helped clear out the root intrusion but maybe needs a slight redesign to enable it to access curved bends without jamming, or possibly a new product for Wardsflex to offer that more easily coped with tight radius bends.
So only four stars because the design limits its usefulness but for accessible straight pipe sections it removed the intrusive roots with hardly any effort at all.
I was impressed by the fast order despatch and next-day delivery that Wardsflex provided during the difficult Covid-19 lockdown and that enabled me to solve the drain problem myself and make a saving against the quotes we were given by the major drain service providers.

i had very high hopes for this tool. it cuts very well but is just flimsy the teeth get bent very easily. i was forest to throw it it the bin after the third use as it was so battered. the outer cutting ring needs to be made of thicker/stronger steel. the idea is perfect but sorry more a toy than a tool
