However, these are quite expensive, so I thought maybe it does the middle class ... it does not.
Unlike the Zeiss cloths using ethanol / isopropanol, use these cloths here the "cheap" nonionic surfactants. Cheaper to manufacture (it takes less and it does not evaporate as quickly), but also just cheaper.
The coating will definitely attack which can be seen after only a few cleaning operations. Not only in glasses, with other optical instruments, these towels engage noticeably to the coating.
In addition, we must not use the towels for LCD displays or the like, my camera lenses I want so do not brush also ...
For the price?!? I see no difference to the cheap towels.
Will probably have to stay at the expensive of Zeiss, with whom I can easily clean with a clear conscience and my lenses, LCD displays, etc. and which are so wet that you can brush loose 2-3 glasses so.
My old glasses were cleaned with the cheap, my new so far only with the Zeiss, the difference is clearly visible.
