This instrument is easy to play and blows with a similar feel to a flute. Liz Goodwin has published a tutor book which uses this instrument as a direct introductory course to learning the flute
The cost of this instrument is only about 7 UK Pounds or about 10 US Dollars - a very cost effective way of finding out if someone is likely to be suitable for a flute
