Have just bought one as learning and carrying around a harp not an option unfortunately. I had one briefly as a student I think but didn’t get very far. It’s very portable and should fit in with my life quite well. And it’s a stick so I can develop a martial art of hitting with it, I mean self defence.

Most important thing I learnt today is that you can make it quieter when beginner-squeaking out louder notes by covering some of the mouth blade (not where you put your lips) with blu-tac.

May post if I get good enough in the future. But in the meantime, this is how it’s done via https://www.irish-folk-songs.com/learning-tin-whistle.html:
