Sooil held the 4th Distributors Meeting in Imperial Palace Hotel from 19 - 21 April, 2010. 16 doctors and distributors from 8 countries visited Seoul to participate in this event. Sooil originally invited 25 doctors and distributors from 12 countries but due to the shutdowns of most of major airports in northern Europe by the volcanic ashes from Island, only 16 delegates could came to Seoul.

Most of participants were very satisfied with the meeting program and the quality of DANA insulin pumps.
