Sound is perfect. Delivery is really fast, it is big plus. Response (I'm not sure the stars in Rate of Response dedicated to Response from a harmonica to me or from Thomann, so I choose from Thomann) from Thomann is ok, but it needs to have a bigger desire to talk with clients. So here is very big minus: I asked to check and correct the tongues at reed plates in every harmonica I bought (3 harmonicas), because I have no skills in this and in my town I can't to trust anyone my new harmonicas. In all harmonicas I almost have not corrected tongues, so I disassemble it by myself and tried to correct with a little stick, like YouTube professionals say. Sound get better just a bit, but it is still not corrected, I am wasting so much air to extract a sound from certain holes (mainly are 6-10), I am afraid to correct it again, maybe I will break it randomly, because I'm not sure what I should to do to correct the sounds. To Thomann before and after purchase I have written summary at least 3 times to check and correct the tongues at plates, but they ignored it. Maybe I can learn correctly with these not corrected tongues, but I have a less pleasure from playing by wasting so much air, because of ignoring from Thomann. Thomann didn't answered me could they correct them or not, so I decided, that yes, like the checking before the delivery. I want, that Thomann take a part in the solving of our problem. Peace and love <3
