Jeff - I think a lot depends on what you want out of the flute. If you’re hoping for something to take to play at bars, in sessions, or camping, then this flute is a big no. While it’s not terribly fragile, a good drop still would shatter the thing.
However, if you’re thinking of playing at home or in calm situations in public, I honestly think it’s worth it’s price. However, it’s not a wooden flute or anything close to a conical bore wood or polymer flute.
With practice, and especially the embouchure tips above, I think it can achieve a nice tone. It’s in tune through 2+ octaves. It’s not the most responsive flute in my opinion, but it’s pretty good for $65 or so. Also, I don’t think the stretch is too bad at all - so if you can play a low D whistle you should be fine. As for the condensation, I’ve never had anyone comment on it. It does collect moisture, and the moisture doesn’t soak in somewhat like it does in a wooden flute, but to me it’s not a big deal.
My biggest regret with this flute is that I can’t achieve a nice, reedy wooden flute type of sound. Maybe a better player like Jessie can, but not me. Also, being one piece of pyrex it’s not easy to travel with, but most flutes under $100 are one piece so the length is a common issue for this price.
Other possibilities for not much more are Patrick Olwell bamboo flutes ($85 or so), Doug Tipple’s PVC flute on eBay ($30 or so),
or any number of other bamboo or PVC flute makers like Tony Dixon (PVC - less than $50 I think) or Erik the flutemaker for bamboo flutes.
If you want to spend more and get a more traditional sound, Tony Dixon makes a 3 piece polymer conical bore flute that sells at The Whistle Shop for less than $200. I know that’s a lot higher than the crystal flute, but enough folks talked about what a nice flute it was so I have one on order right now.
Feel free to ask more questions, and I hope that helps somewhat.
Eric
