Molten Valkeen vs Cheap copy (HRS) - Whistle signals & dB comparision 

Molten Valkeen at Amazon: amzn.to/4b92S5p HRS is available at Aliexpress: www.alibaba.com/product-detail/HRS-Custom-logo-professional-HRS-Grip_1600209066507.html

I have HRS and sound so good and strong

HRS vs Dolfin Pro please

Always Valkeen 💯

They both sound great but i use a fox 40 classic with a cmg and i like it its cheap and loud

I remember seeing a pro-league referees using silver valkeen. Is it fake?

Hello! Im from Portugal, can you tell me a safe site to buy the whistles?

Tại sao ở khoảng cách xa âm lượng của valkeen nghe to hơn hrs nhưng âm lượng db đo được bởi máy thì hrs lại to hơn nhỉ?

ahoj kolegové rozhodčí, kdo má po utkání problém s tím, že mu píská v uších.?

HRS is a lot like the Blazza and the fox forty sonic blast.

WAIT WHAT I HAVE THE HRS ONE?!?!?!?! i thought i had the valkeen

If you are not a referee just you want a whistle for fu the copy is very good for you

Bro now a huazai vs valkeen plis
