I can only say that I am well pleased with mine. Taken the hamster off as I dont like them but as to the way it feels and performs its good to go. OK so I need to charge the batter more often than my MK4 is but thats not a problem for me. I still need a little practice with it to iron out my bad shooting disciple. And yes I think that all said it is worth £1700 that I paid.
