Anyway, I am personally really not comfortable with brands whose main distribution channel seems to be direct to consumer through Banggood and similar sites. I had my fair share of receiving crap and being offered "a discount".
I can deal with it when buying $1.5 ESP8266 modules, but not a $500 scope, that's above my risk tolerance.
a) It's unlikely that you'll be sent a cheap knock-off of a Micsig.
b) You can easily buy from the Micsig official store, follow the link from micsig.com
c) You don't have to accept a seller's offer. All those sites will give you a
full refund if you ask for it.
In short, it's your own fault if you get stiffed on those sites.
