I had asked a couple question on the comments section of their campaign. Without pledging (instant and non refundable on Indiegogo) I could not post publicly, and only 3 comments per day. I asked what was different from other pens (Myriwell) that were found on ebay etc that looked identical. Also, since there is an adjustable temp feature, but not explanation of how that works or is controlled, I asked if there was a button or something.
Here is the email I got back

"Thanks for your mail and requests.Sorry for my bad english… our excellent english spoken team mate are in france until next thursday. i try to answer your questions.New in the second generation are the parts on the board electronic and the friction. the new friction is a better quality for long life. Thats the reason for 2 years warranty.You can adjust the temperature on the button slider under the LEDs on the pen.The electronic heat the system to the melting point temperature."
