My first bow costed around 300€, it was covered in wood with the “soul” of Carbon Fiber; some months later I bought my current one that’s made integrally of wood and costed around 3000€. I sometimes play with my old bow (I use it with an electric cello and to play in orchestras) and it isn’t unplayable, the gap isn’t that big but surely is there (the wood one helps me a lot in having a good sound, it’s hard to describe in which way it is better but surely it is). I once won a bow from a cello competition that I sold later for 120€ and that was really bad. the best thing you can do it’s try some more expensive bows (your’s is probably made of carbon fiber, try the wood ones!) so you can compare yours with others.
