Query: BARELY HEAR THE NOTES

I bought these for two blind children who are interested in music but was really disappointed in the sound quality of the boomwhackers to be honest. One needs to find the perfect place to whack them and then the sound is so quiet that its barely noticable - not worth the money at all!! Steer clear - or as other reviewers say, make your own rather!!
