Top finish, top price! The Winmau Blade IV is the dartboard par. Incredibly thin, well-embedded wire, Crystal Clear optics of each field and good maintenance of darts thanks to the dual core. The first layer consists of a softer, the underlying of stronger material (sisal). No falling out darts, no (to probably very very few) clearance. The Rota-lock system is working properly, the board is as welded to the wall and thereby moves a millimeter, even if you tried it with both hands and force. A top product, I can recommend it to anyone!
