Teufel Boomster Go - give away (Patreon)

This month I would like to give away a Teufel Boomster Go which I found in my cellar by chance when I was preparing the speakers for my pocketsized speaker video recently. Obviously I had got 2 units back then when Teufel sent me a review unit but I never opened the 2nd one and completely forgot about it. This one is brand  new and never used and it should be blue color. 

For those interested please leave a comment and tell me which was the very first Teufel product I ever featured on my Youtube channel. The first one who knows the correct answer will win this speaker.

Good luck!

Update: Winner is Elwin, he was the first one who had the answer correct. Congratulations!
