The Haldzemo 5V 3 Pins KY-008 650nm Dot Diode Copper Head Laser Sensor Transmitter Module for Arduino AVR (9 Pack)" I received are exactly as described.The beam is elliptical, not a round dot and the lens can't be adjusted. These are ment for use in light projects, not for super precice beaming. I can send audio over light with these, so for me they work just fine.

I don't have any measuring equipment so I can't tell if these are as powerful as the specs claim. They seem like fine laser dots.
