I got some extra bucks and decided to buy a Wise 2086. What is the difference between the one sold by TW and the one sold directly from the manufacturer? I'd like to buy from TW but I want to be sure I am not missing anything. Moreover, I understood from another thread that there is an issue with the diablo. What is the issue and how do I know if I get the old or new one? One last question, I have an Eagnas Plus 6500 (it's a crank). The wise should fit without any adapter, right? Thank you in advance. Cheers, g.
