I bought for my dartboard so that stray arrows do not land this ring in the wall. The assembly is easy. The transitions are also barely visible. The ring fits very well to the board Winmau Blade4. Since the transitions of the connectors but are not quite perfect, I can not only awarded 4 stars. Tip: If you want a better look better attacks back to a closed ring. In terms of order process and delivery everything was fine.
