Too noisy - No advantage over normal Bamboo Stylus CS-150

Had I actually hoped for a pen replacement for the iPad to find. Previously I had the normal CS-150 Bamboo with the thick plastic top. The CS-600 in my opinion a handle in the toilet. The cheaper CS-150 works with the Bamboo app better than the fineliner.
Moreover silently through the soft plastic tip. The CS600 is a Geklacker because you constantly deposited on / and the tip is made of hard plastic. Furthermore must connect via Bluetooth to the thing to enjoy everything. The CS-150 is also without electricity. During the CS600 had not detected anything in writing, the smaller CS150 works fine.

For the decision Wisser: Latest firmware, connected properly, the appropriate manufacturers App.

Since I could see no advantages, no buy recommendation. Except for the cool design no advantages which are advertised to upgrade to the small CS150 to the CS600.
