Okay, but needs a better cleaning solution bottle
21 July 2016
This product certainly cleans the sensor as it states (have not tried on optics yet, but I assume it will be the same result). HOWEVER, my biggest complaint (and why this only receives 3 of 5 stars) is that the bottle does not have any method for applying only a DROP of cleaning solution to the swabs! The directions say to only apply 2 drops at most to the swab, but the only way to apply the solution is to open the bottle completely which leaves a huge opening. Impossible to only apply a couple drops this way!
(It may be that you're intended to poke a hole in the second stopper on the bottle, but if that's the case, it's not indicated in the directions. Also, this very much introduces the possibility of contaminants into the cleaning solution, depending on what you use to poke this hole. Not ideal at all!)
