### ⭐⭐⭐⭐⭐ Does the job perfectly

### ⭐⭐⭐⭐⭐ Superb

Top quality at a great price. Used it a few times and it's perfect.

### ⭐⭐⭐⭐ You would think it would be simple
*by M***G on 8 September 2018*

When assembled with the right string, its 100%. As others note, getting the string in is a pain. My solution was poking through with a bent paperclip, but the supplied string is so fine that knotting it big enough to prevent it slipping out is close to impossible and having done it, the bob cocks over to one side opposite the knot. Useless. Throw the supplied string away and poke the thickest you have got through the hole and bob is now your uncle.
