bought to use in school playground, very effective gives a good sharp loud sound.

Grandchildren loved them! The reason I only rated them 4 stars is because one whistle fell off the cord on first wear. Luckily I spotted it! Otherwise very happy with purchase and very pleased to find non plastic whistles.

Perfect for deafening HMRC, internet provider, Amazon phonecall scammers! Only got a plastic pip in it, but it does the job. Very good value for money.

I bought these as a joke present for my husband's birthday, however we now have them on standby next to the landline phone to deter scammers. Just have to check before deafening a family member....

I bought these to alert neighbours in case I have a fall, and to blast down the phone at scam callers. Perfect for both uses! Sad to see a plastic bead has replaced the traditional pea in the whistle bit it works just as well.
