I like how solid this 2x-AA light is. It feels like a well-made tool to my old hands. It's lighting modes are very good for my needs. What I didn't expect is the controls are the opposite of my rechargeable light. This light is going into my SUV, to replace the old 3x-AAA Mag-light that is starting to corrode inside. This new light was tested for hours, with old weak AA batteries and did very well. It's not going to get a lot of use, and will be inspected every few months for any sign of AA leakage.
