HipatWhistle, 6 Pack Stainless Steel Sports Whistles with Lanyard, Loud Crisp Sound Whistles Bulk Great for Coaches, Referees, and Officials

I gave 5 stars on this one, my dog react perfectly well to it, really good value for money, perfect.

I work at a football stadium and laugh myself stupid when somebody asked me if I had a football whistle and when I asked them why they don't sell them in the shop I realised why selling whistles to 12,000 fans attending a football match would not work out well. These whistles are excellent good quality very very very loud cover ears I love them.

Very loud hood perches

I was ‘blown away’ by this product. Great value for money and I have a whistle for every day of the week…except for Sunday as that’s gods day and I don’t think he’d want me blasting that thing all the live long day

I bought these mainly for emergency use. I haven't owned a whistle since I was at school, and was surprised by their compact size and light weight. I was utterly unprepared for just how loud they are (I blew one indoors the first time). You would easily hear them at the other end of a sports pitch, and they give a very crisp, clear sound. Being stainless steel they should last for a long time, and the price of them means they are very good value for money. I would thoroughly recommend them.

The whistles are made of steel and should be strong and durable. I look forward to testing them out at the weekend.

Whistles were used by marshals in a charity cycling challenge (not a race). They are really good.

Pretty unimpressed with these as they're just so poorly made and look dreadful. I bought them to laser onto to use as promotional items, but they're just not good enough. The whistle is loud, and usually works.
