I was using a just regular stainless steel drinking strap but this is so much better and I got the cup set too which gives you a lot more back pressure which can really help increase your range.
These tools are utterly indispensable and I use them for each and every vocal warm up session.
I would not be without the voice straw and can attest to the benefits of using straw combined with water. Really really helpful for any serious user of the voice.
Also...I found customer service to be very positive. They are hot on the comms.
This is a great tool for flutists as well - helps with projection and resonance as well as the coordination of all the inner workings involved in playing the flute (encouraging the release of throat tension and orienting the body for proper and effective abdominal support). Thank you! Highly recommend!
