Is the contact technology any different from the Deger?

I had a Deger for a while and got rid of it because with skin as dry as mine, I couldn't make it work reliably, and not at all with normal mid-joint fingering - in ordinary Scottish weather it only worked with my fingertips. It was a pain having to use moisturizer all the time. (I have a picture on my website of me playing it around midday in midsummer in the ruins of the mediaeval university of Harran in Kurdistan - worked great there since it was 45 Celsius).
