I have a few different shakers and decided to get a rainstick/rainmaker as well.
You can really hear the sound of the balls inside hitting the spikes in this rainmaker, and it sounds "wooden" rather than plastic or synthetic.
It also sounds great as a shaker, a bit of a warmer/woodier tone than other shakers, although a bit cumbersome compared to an egg shaker!
Feels nice quality. You can draw out the sound for at least 20 seconds (I think 40seconds was the longest I managed to get out of it), but it pays to have a longer rainstick so this one ticks the box.
Can't go wrong for the price.
