I can not see any difference in quality for Grand probably second-best professional Dartboard Unicorn, the spider is also embedded nice and maximum thin so that a clearance is very rare. The sisal runs also beautiful back together, with the area around the Triple 20 suffers over time, but that's with any Sisal Board as, for eternity, these just are not, after about 6 months intensive games you have the first time the Turn ring and lay the 20. However, casual gamers have many years of enjoyment. It's just a difference whether you train every day 3-4 hrs. Or only on weekends a little time with friends playing it.
A concise manual is, as the fastening material, only an anchor to bräcuhte yet :-)
In short a good dartboard, I do not expect more from a disk ....
