MFH Emergency whistle - Olive

You need to take a deep breath and blow very hard to whistle. The keyring is probably the weakest part, it’s worth changing it. You can put a child’s details on a note inside, close it up and nothing will get wet. This is a useful product for increasing safety in case a child gets lost.

The whistle is very loud, which is an advantage. A plus is the keyring and the option to unscrew it. You can use the included note to insert your details inside. However, I give one star less for the fact that you have to blow really hard to get that loud sound – it may be too difficult for children.

It’s fine for adults but I don’t recommend it for children – you have to blow quite hard for the whistle to work so a child might not manage. However, it's loud, solid, and you have the option to write your personal details inside.

Metal whistle with a keyring – very solid. It whistles loudly, and a big advantage is the option to unscrew it and hide, for example, a note with personal information.

A ball-less whistle, designed so that it does not require much force when blowing. It emits a loud and clear, high-pitched sound that can be heard from a distance and is very distinctive. The large, non-slip grip makes it easier to hold the whistle in stressful situations or for people who are cold or have motor difficulties. The mouthpiece has a grooved surface, making it easier to keep the whistle in your mouth.

Very well made, lightweight and aluminium, so it’ll last a long time – you can’t break it easily. Most importantly, it whistles well and has rings for hanging – mine hangs on a Mil-Tec lanyard with a carabiner, they look great together. Plus for the note inside for writing details. I recommend it. In my opinion, better to invest in an aluminium one than a plastic, as it will last longer.

Although it’s a simple gadget, it’s very practical. It helps to deter or can be used for signalling and establishing your location from a distance. There’s a space inside for contact details – especially useful if giving the whistle to a child. Well made, compact. You should definitely have it. I recommend it!

The whistle works in many situations – from calling your dog to signalling danger. Strong construction and a compartment for a banknote allow you to hide small items, like matches. Loud sound and a waterproof compartment are advantages for tourist gear. It's practical, durable and lightweight, so I recommend it for everyday use. A really great EDC addition!

I am pleasantly surprised – the whistle is great, metal casing. I bought it for my daughter. It's really loud, and the ability to hide something inside is a big plus.

A solid whistle. You can feel its durability and weight when handling. The option to put a note with your details inside is great. It will work well both for tourism and for extra security. I recommend it.

A lightweight whistle with space for a note with personal details inside. Unfortunately, it's not very sensitive – you have to put in the effort, take a lot of air in, and blow hard, especially when you’re already tired.

The quality is fine, but the sticker may eventually peel off – the corners were already coming loose at the start. The ring and chain are quite delicate and thin. You can hardly fit anything but the included note in the compartment. The whistle isn’t small, it’s bigger than I thought. To make it really loud, you need to blow harder.

The whistle does its job, I see no reason to complain ;) It works as it should, and those looking for flaws will find them everywhere ;) It’s a simple and inexpensive thing that's worth having. I recommend it.

A decent, although not outstanding whistle. Probably more suitable for adults, as you need quite a bit of force to blow it, and children with small lungs may have trouble. Even so, it's worth having such a whistle at hand – it can be helpful if you find yourself in an unfamiliar place and want someone to hear you.

It's a good whistle, worth having in your gear.
