Don't fill it up too much. Usually 2 tbsp suffices, otherwise the mesh clogs and water cannot pass through during shaking. If you want a stronger grog, just use two AluBalls. Take lukewarm water, and don't shake too vigorously. AluBalls are pretty durable from my experience, but especially when using two AluBalls at once you have to be careful. As for the shaker bottle, the Kavafied bottle is fine, but in my opinion the bottles from BlenderBottle are a bit better.
Besides this general advice, there are plenty of threads about the usage of AluBalls in the forums. Resort to the search function and you shall find.
