Hullo! The boards are very good, superb! But description and photo are not exact! It is necesserely to ask seller twice-three times. I suppose that manufacturer must describe his pieces yourself, he must give exact board number and provide with exact firmware ( point out the site or give CD !) The seller loses many buyers for this reason ! Shortly, boards must be sell with firmware! I hope further to ccoperate with this shop, Yappy New Year! With respect Kovalev!
