I have this bow for 6 years at least, and I have to say that I'm quite happy with this purchase. It is super light compared to wooden bows, and it is enough for me to use it as my primary bow or a secondary one.
The first hair that comes with it is not particularly good, and seems to be synthetic, but with a simple hair change it is all good.
The only bad thing that I can think of is that I noticed a slight camber in the bow, after quite a while that it was sitting orbeing used with half the hair on it. So I can't really be sure that it is the material's fault or mine that I left it for long with half the hair,so long that it drew the bow to one side a little...
