Molten

Simply the best in the business. Used by the best referees in the world - Cuynet Cakir, Felix Brych, Bjorn Kuipers and more for good reason! Very easy to change the tone of the whistle and to signal multiple blasts. The finger grip is also superb and a very good upgrade over the traditional wrist lanyard. The fact that the whistle is that much more expensive also means that you are much more likely to be the only official to use it in your league - working as an advantage helping you to stand out even further! A full blast before KO to signal the captains and a sharp signal to start each half tells everyone around you just who's in charge! £44 approx might seem a bit steep for a whistle but this whistle is of the highest class and is excellent value for money.

I ordered molten blazza for a friend that plays basketball and it appears in my search that the picture is molten blazza, I ordered it asap because it was on prime but when it was delivered it was a molten valkeen for football, I purchased this blazza in 2015 for other friend he loves it till now

I used to use the Fox40 collection but decided to try out the Molten Valkeen. This whistle is the Best! The variation of sound it offers is unbelievable, especially on the field. Definitely recommend it.

not very load

Worth every penny. Truly professional. If one can afford then do not hesitate

I love the molten dolphin valkeen and this is my second time ordering it. I ordered my first one for £80 but I got this one 2 years later and it’s only £40

Very very good

I feel like the Valkeen is Molten's Competitor to Fox 40's Sonik Blast. Both whistles boast a loud sound that projects. In the end, I think the Valkeen comes out on top. The Valkeen is very loud and full, that's expected. It's fuller than the Sonik Blast, and a bit more responsive. This makes it superior all around. Now, this is more expensive than the Sonik Blast, but it is worth it. The higher price tag is justified by a quicker response, more versatility (as long as you blow it correctly, you can use it indoors if you need to get someone's attention - maybe you're in a school as the gym coach?), and being easier to use. Unlike the Sonik Blast, this has an easier design (you can always find which direction is up). This is also a lot more durable due to it having more metal parts unlike the Sonik Blast. I mainly use this whistle as a crossing guard whistle (which you'd need to be a bit loud), and calling kids in from recess, and it's not failed me. It's tough to ignore. I highly recommend this over the Sonik Blast!

Producto original, de gran calidad y potente sonido. Los soportes de goma son cómodos, aunque se ven algo sucios.

サッカー審判用で購入しました。 サッカー審判では笛を予備含め2つ用意する必要があり、メイン用途で購入しました。 良い音で満足です。

Il fischietto rispetta le caratteristiche descritte. È molto potente e fa sentire tutti i decibel che dichiara. Forse il materiale, nella parte che va in bocca, poteva essere protetto meglio dall'aggressione dei denti. Tutto sommato è il miglior fischietto attualmente in circolazione, e devo dire che ne ho provati tanti.
