"Just a quick note to thank you kindly for your support and customer service in helping me with the new sunnies! I bought the pair of Trakker in copper you recommended for me and you were right they were the perfect fit! I have never had such a comfortable reassuring fit from a set of sunglasses ever! That said the lenses on these are absolutely incredible!! It is effortless on my many hours of driving with work to look through them and for the first time ever I don't feel as if my eyes are straining to "see through the lens.." As you told me you could help with! The driving strain headaches are finally GONE! I haven't had a chance to fully test them on the water yet as central Vic is unusually under flood, but test looking into the murky water I can already see how great they will be! And can see good sub surface depth even in dirty flood water. I truly thank you for the old school customer support! It goes a long way in my eyes and because of this I have been and will continue to recommend Tonic sunglasses to everyone! (Any easy thing to do when a product is so good!) Thank you once again Doug and I look forward to wearing Tonics for many years to come!"
