The technology itself works quite well. I did not like feel of the pen. The roller was approximately bic quality which is unacceptable for a $200 pen. My pen died after a couple years of virtually no use. It would probably require a redesign of the pen, but I find I prefer gel pens nowadays and wish there was a gel pen insert.
If you REALLY REALLY need to take notes during meetings, its the best thing ever. I find in most meetings however, there's probably one or two facts I really need to know. I decided that instead of taking notes I would just stop caring about meetings. I enter those one or two facts into evernote on my phone and I'm done with.
