Most important: the quokka is perfect! It is very well done regarding design and quality, and it really looks cute.
The whole buying-process was excellent as well:
I orderded the Quokka via this site. The seller gave precise answers to all my questions in advance. After one week, my quokka was ready and the seller sent picutres to me. Paying was easy via paypal. The quokka was sent by russian mail with assurance (extra fee) and tracking. The quokka arrived here without any problems or damages.
So a seller/ produces I can recommend!
