Another, completely different point.

You have a brand new wooden instrument. The need playing in. They will not take the abuse you can hand out to a cheap whistle. About 15 minutes a day for the first week, gradually building up over 4 - 6 weeks until you can play it all the time. There is advice on Phil's website on playing in new instruments. Follow it.

It will also need oiling from time to time - about once or twice a year is enough.
