Wera Tools UK - JOKER combination ratchet wrenches/spanners

This is a neat idea for a rachet spanner http://pmmonline.co.uk/products/wera-tools-uk-joker-combination-ratchet-wrenchesspanners

The video in the story explains what it is good for.

Has anybody had experience with them and can you suggest a good place to buy them?

Some neat applications but to be honest, I think that they may have some applications in the film for which there isn't an existing problem. I'd use a conventional ratchet spanner in most of those applications. For a proud bolt, I simply put my thumb on top and ratchet away!

I do like the idea of putting a nut in there so that you can feed it into a tricky spot. But again, I just stick some tape on the spanner. My local place does Wera so i shall have a look at them next time I drop in.
