kerry,

I do not have any negative comments about the one I owned. Heck, I even dropped it out of a treestand once. The mirrors and lenses inside became unattached to the housing so I had to take it apart and " reconnect" them. It worked perfectly fine afterwards and it gave me a little more confidence when I was unsure about some of the various shots that I had from my treestands.

For $40 or whatever they are charging for them nowadays I think they are worth it.
