This rosin is fantastic. It grips the bow extremely well and glides on the string like butter. The maker of Melos rosin is a really nice man, and they always make the rosin fresh every order with the highest quality tree colophane in Greece. The web page they have is really easy to manuver and tells you the process of them making the rosin. It also doesn't have any extra ingredients like glucose in it so it helps with the quality and dust, and each cake I've gotten has a nice fresh smell and amazing colour. Using this rosin is a pleasure and I would recommend it to anyone! I would like to note that there is a dark version too, made for winter, and the light kind is made for summer.
