The crusher board is great - solid and excellent value. The only thing to think about is how solid/wide your architrave is on your doorframe. For us the board is super solid when used on someone else's normal width properly put on doorframe.
However, in our silly rented flat with cheap everything, the frame is very narrow so it feels a bit unstable and walks a bit so you end up doing fingerboard on sloping pockets...!
