The 5 watt infrared is a vast improvement over the lower power 3 watt leds used by other devices, with brighter intensity and longer *. A minor issue.

They are very comfortable for this petite gal! They came packaged well. If you know how to set them up, they are crisp.

Good low light performance, clear glass, adjustable eye pieces, right eye parallax adjustment allows really good clarity. But thats to be expected by their objective lens size. Optics are clear and easily adjustable.

My biggest complaint is the pos ( piece of…. This item is by no means worth what i paid for them. Not worth returning. Very misleading product description.

Full open the product does not allow full eyesight coverage of face. I am sure that they do magnify as promised but i have no concept of how much magnification would be needed.
