They arent cheap, but i love mine! I just feel i get more range in tone when i use it compared to a fox. Plus when you blow it, people know youve blown it!!! The other added bonus, you wont hear many of them about, so no problem on a busy council pitch in distinguishing whos blown their whistle. No mistaking the tone of itJust looking at one of these valkeen whistles - is the pricetag purely based on sourcing and importing or is it genuinely worth an extra 40 quid on a sonik blast for example?
