Compare old and new HX6932 HX9110

I have been staying Sonicare toothbrushes, and change always to the new model.
Previously I had the HX 6932 and was very pleased. This one, the HX 9110 has some improvements that are not necessary, but useful. For all new buyers: the old do it well and are cheaper :-)
Does the new as opposed to old following new features:
-lt. Information, better plaque removal
-An extra program for whiter teeth
-6 Instead of 5 brushing modes
-the new intuitive pressure sensor
-almost 30 minutes more battery life
-beleuchtete Function Display (what I do not understand, because the old one was also illuminated)
It is powerful, lightweight but thick and without silicone handle what the attitude was unusual at first but as the silicone after 1 year no longer looks so beautiful, it is now so convenient.
This model has a slightly different design and has now (instead of: clean, sensitive, massage, + 2Reinigungsprogramme) Clean, White, Gumcare + 3 intensity settings.
As with the old here is the processing, the keys, the cleaning result and the battery life Top!
Supplied with a replacement brush head (there are others to buy, but they are currently my darlings), a practical storage box and a charging station, which can sichverkleiner.
Although it is an expensive purchase and the brush heads are not cheap, I will always stay with this company / brand, because I've only had positive experiences.
