This is a well built flashlight and is easy to use. The variable feature is nice. The one thing I don't like is the way the lanyard attaches, so I leave it off. This design needs to be changed.
This was a replacement as my old one's on/off switch was worn out after many years. The variable light is great but this new one has a couple things about it I don't like 1) It takes a lot of force to get it from the off position into a lighted on mode. The opposite situation I had with my old one - you never knew for sure if it was in the off position because there was little indication it was in the detented off position.2) the little protusions for grip on the wheel are annoyingly sharp, unlike my oridginal one. To solve both problems I find it best hold the flashlight with my right hand and adjust the wheel with my left hand perpendicular to the wheel-like your fingers are turning a dial instead of rolling the wheel with your thumb.
