As reviewed earlier, the first Coruss bow I received would not allow me to tighten the bow hair properly, I emailed Coruss and after exchanging information Coruss sent me a replacement bow (free of charge), and it works as expected. The screw is still tight and a bit hard to turn, but it gets the job done.

The bow produces a clean, sharp knife edge sound compared to my wooden bow. I like all things carbon fiber--i like appearance of the black CF stick and red hair. In regard to playing, it is light and well balanced. I lent it to a professional, and they were not as pleased with it, basically gave it two strokes and handed it back. It is not as forgiving as my conventional bow, but I carry both in my case. Just in case. Thanks again to Coruss for kindly and quickly resolving the issue I had with the first bow.

An sich bin ich mit dem Bogen sehr zufrieden. Das Einzige, das mir nicht gefällt, sind leichte Nebengeräusche beim Streichen.

I am satisfied with my purchase, they are beautiful and have excellent sound stability

So, from what I can tell it is a good bow. However, for some reason, the bow screw reaches the end of its travel-threads before the bow hair is sufficiently tightened. And so far Coruss has not provided an answer. It is my opinion, as strange as it sounds, that the bow hair is too long for the bow, thus the screw reaches the end of its travel before the hair is sufficiently tightened. But who knows...tic tock

From my first impression and experience this bow is incredibly, super comfortable, well built and balanced, also the hair super smooth and grips so well making the experience of playing so perfect. Thank you so much for this amazing opportunity to have it!! Success
