From old to new 1

Previously I had the handpieces probably thrown away and bought me quietly grumbling new - so I've been saving for a bit of internet research and an hour on the workbench (45 minutes for the first and 10 min for the second handpiece..) Well above 150.00 ,
After the how-to has already been described by several other reviewers, I can save larger versions to. Perhaps one solllte ever have had a soldering iron in his hand, if one dares to tinkering and - important! - Take plenty of time if you do not handled every day with such things. The most important thing is to pay attention to the very small wires down on the lid, the same tear off and have to be brought only with great effort again to the right place - I speak from experience.

Otherwise, you can hardly go wrong.
