Nice dude-highly recommend! P.S.-made the line to contact another unfair store April Li (store: Five + tools store). This crendel threw me at 631 rubles! So be careful! Trades similar but defective goods. When filing a claim includes a fool. Because of his behavior, I am forced not to cancel disputes with decent sellers, as I am afraid that I will be thrown!
