Good Adapter with super value for money

The hex adapter fulfill their function and are built very robust.
The ball has a strong pressing force, so keep the bits securely.
Only downside is the susceptibility to rust - if the adapter to get wet
(They have used in the rain) they start after just one hour to rust -
is not really tragic, but I would have expected from Hitachi better coating.

Nevertheless super bit adapter and full points - at the hardware store each of the three adapters already cost many times over!
