Whistle, 2 Packs Plastic Sports Whistles with Lanyard, Loud Crisp Sound Whistle Ideal for Coaches, Referees, and Officials

Suenan fuerte. Cumplen su cometido. Tan simple como un silbato con su cordón.

Wow! A gentle blow and out comes the loudest whistle, not complaining they are great! Excellent value for money, very well made therefore good quality whistle!

Funzionali, presi per mio marito allenatore dei bimbi a calcio. Suono forte e squillante

These whistles arrived, and they work exactly as described! The size is perfect, and the included lanyard means I didn't have to take one from any keychains around the house. The sound it makes is very loud, which will be perfect for coaching my kid's basketball team. It looks good, and is also made of plastic, which is nice, that way I don't have to worry about it accidentally hitting a kid (since it's not made of metal) when getting close to them. Overall, it's perfect!

Très bien, le son est bien plus fort que les autres sifflets que j'ai eu jusqu'ici. Je recommande.
