More than I'll ever need!
As usual with these sets I actually only needed 4 items, but at least the choice here let me easily select the best ones without guesswork and the price of 4 alone was near the same as this kit. Quality seems fine.

Perfect little set
Exactly what I needed. Large variety of lengths, more so than you realise when quickly looking at the pictures! The plastic box isn’t fantastic but I didn’t buy it for that.
