Kstruch...The basis for my feelings is not from wearing it, but seeing others wear it prior to my purchase. Just from an observer, I strongly feel they are very effective. I saw that cyclist way up ahead. I saw that person so far ahead, I was unsure what It was; up until I got close.
Will check out your web site. It the US supplier affiliated with your product. Design looks a little different. Traditional vest with one stripe that flashes. Horizontal stripe about the base of the backside of the safety vest...that flashes. The stripe is supposed to stay illuminated for like 300 hours.
