I purchased Waltons Irish Penny Whistle - Key of D D for travel since I did not want to risk damage or loss to my handmade bamboo penny whistle that I already own. I needed something sturdy with a fairly descent tone, and have found this instrument to be sufficient.This whistle is more sensitive and less forgiving than my bamboo whistle. If you do not fully cover a hole, or you blow a bit too hard on the low notes, you will know immediately as this whistle will make an annoying squawk. Because of its sensitivity, it is helping me learn better breath control, and keeps me more conscious of my finger pressure. The holes in this whistle are pea sized or smaller which makes it much easier for people like me, with small hands and fingers, to play. This might make it an excellent choice for a child's whistle as their small fingers would be able to easily cover the holes. My whistle is sightly out of tune on the D note, but it is not too bad, and still works well as a practice and learning whistle (my bamboo whistle is for performances).
Waltons Irish Penny Whistle - Key of D D is very soft; much quieter than my other. Because of this, it might work well for someone who has to practice indoors since it won't be too loud so as to disturb others in the house/building.
