Works - Redfield Raider 550 Laser Rangefinder

I had to send the first one back, as it had a big-enough black dust piece on the internal lens, somewhere.

Second one had just a small piece of dust, internally. I kept it, as returning cost $10 UPS.

I haven't verified its accuracy via tape measure, but it seems to generate readings, just fine. In fact, it works through window glass, which I had not expected.
Pros: works as expected
Cons: internal dust
