Do they work or are they a con?


They are of NO USE whatsoever. The lens has a little ' wall ' around the
edge of it, which just serves to deflect the brush bristles so that they
only touch the very centre of the lens. I have also had these lens cleaner
discs actually cause damage to the laser, as a result of the brush bristles
getting caught in the cover which surrounds the lens, and pulling it off.

Cleaning the lens properly using isopropyl alcohol and a cotton bud is not,
in most cases, hard to do, but if you don't feel confident to do it, take it
to a professional.
