Bought this for my son for his fifth birthday. The different elements of this toy are great and really fuel his imagination. Horse reins, saddles and 'cloak' fit most other PlayMobil horses (other than ones which are harnessed to wagons and so on) giving further flexibility. We have a lot of fun with PlayMobil pirates usurping the throne; the rightful king escaping in his disguise and the castle being ambushed by the bin lorry (with soldiers and crossbow hiding in the back)! Perhaps we're both as mad as each other, but it's the flexibility of PlayMobil that affords these possibilities.
Sometimes you can wonder just what you have paid for with PlayMobil - it can be a bit expensive - but this combination is well worth the money.
Durability wise, as with most PlayMobil, this is fairly good;the arrows and quiver are the weak area. As long as the arrows remain in the quiver (!) I can't foresee too much of a problem, but they're perhaps a wee bit delicate to be removed often and remain connected.
