My friends tell me I sound “smooth as chocolate” when I sing after using this. Haha. Only down side was shipping. Paid for 2-day but it fell on a holiday weekend so it took 5-6 days to get to where I was. But that’s just USPS for you so it is what it is. (This was not the voice straw company’s fault) Overall great experience with my straw! I am telling all of my singer friends about this
