When considering the diferrence between available devices a recent story from BC is important. Ten years ago Chris purchased his device from the Cloverdale BC Pharmasave location, having moved to the interior of BC he called Dianne at our office and just purchased a replacement. Certainly not all Owls will last ten years, but the long term devotion and wearing of the device goes a long way to explaining the difference that the Owl brings with it’s proven background from the professional Silencer device family www.the-silencer.com or www.drhalstrom.com
Dr. Halstrom really did get this invention right!
