The switch on my Wizard Pro at times was very hard to engage, and yesterday it did not work at all, Even when I used a blunt stick to try and get leverage the switch would still not work so I had to unscrew the tailcap to get the light to go off. I contact Armytek and am awaiting a response. Is this a known problem at all? I purchased the light from illumination supply. It has always seemed pretty firm but last night was the worst. Today it seems to still be a little hard to engage, but functions correctly. Anyone have experience with this?
