First, I like the concept of the gag prop and had plans for it but after receiving it, I'm not sure
I'd want others to use it as it would be hard to clean. The product looks like a demo piece that
never made it into final production stage as it was made with a 3-D printer. It's a great example of
3-D printing but that's not why I bought it. 3-D printing is great for a demo but shouldn't be sold
as a final product. They say you can just wash it but the interior and the exterior are not smooth
at all which I see as a cleaning issue since people are blowing on it. I'm glad that I bought this
as an Open Box item otherwise I would have been sorely disappointed. Definitely not worth the full
cost at the current quality. If production had been made better as a mold and it looked like a
normal smooth plastic whistle, I could back the price. It's just my opinion and maybe others won't
care. To me it doesn't look very professional, they need to find someone in China to produce this
for them that can make it smooth. The video tutorial was fine and instructional. I really did want
to like this but it's just not ready yet. Hopefully, I accidentally got a prototype.
