Review on 🔔 Coghlan's Function Whistle: A Reliable and Versatile Outdoor Survival Companion by Matthias Foxx

Bought two of these in one order. My daughter wanted the children's version, which costs almost twice as much. They are identical except my adult version is black and their child version is yellow. Same body size and such. The only difference is that the children's version says "KIDS" on the packaging. They have the same sound, same volume, everything. Both compasses work and are filled with liquid. I had to buy two adult versions, but it's nice to have two different colors on hand.
