Top whistle!

I use this whistle as referee. It requires very little air to very loud sounds produce. Especially in a noisy environment in the game is now all at stoppage. It has never been easy on playing. It is very handy
and well made. I recommend it to our young referees who I accompany as "godfather". Some dare not really let it fly to blow when the situation demands. But once tasted blood, they enjoy it. Forceful clean bubbles should refrain at close range of players because they just cringe so. You can use the whistle in the hall when you whistle with about 30-50% strength. Yet another advantage: Unlike many other pipes it does not go on your own ears, especially when the whistle goes, but scatters beautiful way forward. Conclusion: It is not always serious Fox 40! So at least 5 Stars.
