About HE-400 issues, we have found out the reason of the problem. It is a design flaw, not a QC problem. We have made a significant prograss on fixing the problem. We are doing a comprehensive test of 2nd batch drivers. We will finish the test in about 2 weeks. Hopefully we will try to ship all orders before the end of Feb, 2012.
