I got a general mini from a member - and had another 2 on route from Aliexpress. At first I wasn't all that impressed with the general (ergo) just felt awkward. When teh 2 others arrived which were non ergo they felt so much better - so I stripped the ergo naked and it feels pretty good - so went on to strip one of the non ergo's and it also felt good.
All 3 shoot very well for their size.
Not sure how the butterfly feels TBH - but the general mini is a nice shooter (with a pinkie lanyard). I'd suggest getting 2 as getting rid of the wrap may turn it from an OK frame to a much better one.
Only thing that I find strange is the cost from DK - they seem costly for what they are.
