Thanks André.
Yes, I have the old version and have had no problems.
If it ain't broke, why did they ' fix' it?!
'Cos they're German. They routinely invent, design and make something superior, and then fuss with it until the second edition is not so good. Another example is the BUMM Cyo lamp, of which the first edition was the first grown-up, adequate hub dynamo bicycle lamp, the second edition was rubbish, and from there they gradually recovered until the current edition (Premium) is at last superior to the first edition. You have to pick your German components' production date carefully...
