I was perusing Big Whistle’s website and noticed that they had the Syn D/C set on offer, so as a Syn fan I bought it.
I bought it at 2:30 in the afternoon and it arrived at 11:30 the next morning.
Excellent service Big Whistle

I agree with this 100%. living in California, I did not get my whistles from them the next day, but I got 'em quicker than from a lot of places that I’ve ordered from in the US (AND their shipping charges were less than $10).

Same for Russia. Bigwhistle is faster than many 
My favourite whistle store. I’m a very satisfied many-time customer. Great service.
