Radp might not have subscribed to this thread (if so try to private message him). Also not everyone are always connected to the internet, might be his case. And in his own thread about silicium, etc. he did not seems to really like questions.

However I don't know why he would lie about him trying Bioptron, but who know. ;-)

When you will try it, I am sure we will hear about you though. I understand however that you have not setup a date for your Bioptron experience yet? Are you planning to or still gathering information?
