Delivered OK as part of another order. Seems mechanically robust. It could do with a screw hole that could be used to also enable it to be attached to other types of rods, other that threaded rods.

### ⭐⭐⭐⭐⭐ Well made, easy to use and very good value
*by D***E on 22 April 2017*

I bought this at a cost of £3.05 (21/04/2017) through Amazon with it being referred to as an ADD-ON item which applies to Amazon purchases with a value to £20 plus. Strangely all the add on bits arrived today 21/04/2017 with no delivery of the Prime item and it's promised next day delivery promise to amazon prime members. This just reinforces my experiences that the next day promise cannot be relied on. The double worm screw screwed unto my drain rods with no problem what ever. The fit was both nice and tight and deep so that I had no fear of the dropper undoing itself in the event that I had to manipulate the rod in an unwinding manner. This is made of what appears to be a decent quality metal. The joins to the screw on head are well made. This item was delivered alongside other purchases in a super fast less than 24 hours from order to delivery. I have had it in my possession for less than 8 hours and having used it at my sons home, have already completed a job and saved a potential fortune OVERALL, very good value, well worth the purchase cost especially as a delivered so promptly item.
