I have been using this for around 3 years now and it has been used hard as you can see by the state of the bits.
The kit of bits is in a nice flat pack that has a positive click to open.
The bit holder is really good to use.
If you drop a bit into the holder it gets pulled in magnetically, but you need to pull the outer knurled ring forward to positively locate and lock the bit in place.
Price: Set approx. £14.00
I have used this set for around 3 years in a number of portable drills and in an impact driver.
It is still working very well.
