I have not tried one yet. However, I have been connecting with their Twitter account to inquire about new products etc and they offered to let me try a Heaven Wood (7w at 5w length) as a demo. I’ll most certainly post a review after I’ve hit it.
I’m VERY excited to have the legendary customer service from DTG/Sub70 now running SMT. I really believe they can compete with Maltby with quality affordable components when they turn over the product lines.
