Been using this for a while now to fill some quite parts of my band's songs.
Quite impressed with the loudness and clearness of the sound of this octagon shaker. Been using some egg shakers before buying this and I needed two or three of those to achieve a good volume. This octagon shaker is loud while retaining a nice round and crispy, high quality sound.
Moreover I find it very easy to handle. Easy to add some versatility in your playing, and adjust the loudness and tone.
