This is just the ticket for peeking into my cases after a powder drop. There's plenty of light to see down into the brass from just about any ram position, and it doesn't interfere with primer feed mechanisms. The adhesive strip could be a little stronger, as the power cord can easily dislodge the strip. I secured mine with two small zip ties.
Pros: Powerful illumination, no batteries.
Cons: Self adhesive strip is weak
