Review title: Light spot is terrible
Product review: Barrel is solid. Excellent fit, finish. High grade machining and knurling. Why the big neg? The light spot has ~6 dark rings. Looks like an interference pattern. The rings exist both closeup and far away. Totally unusable except for taking a quick peek in the dark. I don't know if it's the design or a defective unit. I've returned it and don't plan to order a replacement. I'm very happy with the 2-AA unit and will probably order a second one. It's bigger of course, but still compact.Note added: 5 star for Amazon customer service. They picked up the tab for return shipping and gave me a refund within a week.
