An absolutely fantastic buy, I wanted something cheap mainly because I haven't tried sound eggs before but also because I only needed them for one song. Having used them for a while now and gained experience with them as an instrument I'm finding holes in my setlist for them again and again. Very versatile, an excellent tool for any percussionist (or any musician for that matter).
Just one thing though, make sure you specify the colour you want (details on the page I think) because they can come in a rather disgusting blend of lemon yellow and ice blue 0_0...
