Shipping to Germany without problems. Low-tech also means no hassle with customs! Product has a very sturdy feel to it, I have great confidence in cramming it into my key pocket with all the other "sharp&scratchy metal objects" (as opposed to other esp. electronic means of two-factor-authentication) Documentation is very basic to say the least - there's one relevant video on youtube. Apart from that, only a small strip of paper with the ring layout as a backup comes with the delivery. Idea for improvement of the product (p@ss Mark III?): Make the individual wheels snap into position for a better haptic control over positional change. Wheels loose their position very easily when handling the Mark II key fob.

Thank you so much for the review! You are not the first to make this suggestion; if it can be done affordably, in the next version I will add detents so rings click into each position.
I also need to improve that video :) Thank you for reminding me.
