I work with kids who love different and unusual noises. One of the kids loves these toys but due to excessive use my old ones were beginning to wear out. I bought these as a replacement and they were really not worth the money. They feel cheap and the noise was not very loud (really clunky and not smooth). I ended up returning them and getting a different set for a better value that was also better quality. Eight dollars a piece is excessive especially when they perform worse than the half broken ones I was trying to replace. There is another option for gravity tubes that comes in a 4-pack for around 14 dollars (Toysmith Spiral Gravity Tube #9295 4 Pack) which is a much better value and better quality.
