At last,

[Norman Verona]

My Ryobi electrics screwdriver has died, my Black & Decker only screws for a short while so off to Brico Depot for a new one.

 

Found a Bosch 3.6v unit with......

 

A cartridge loaded with all the bits I'll ever use. You slide a slide back, a light comes on in the magnifying glass that allows you to view the bits. You rotate the cartridge to the bit you want to be loaded and then close the slide and hey-presto.

 

Now that's a good idea that took ages to come about.

 

Unless you now tell me it's been around for years.
