I had a couple of smudges on my a6000 camera and needed a sensor cleaning kit. I watched a short video on Youtube on how to use this product and had no problem cleaning the sensor in a matter of minutes. Good instructions and the packaging was excellent. I would recommend this to anyone.

I've found that this type of swab, along with a pure methanol-based cleaner, is safe and effective for 1.6X APC size DSLR sensors. They are individually wrapped to keep them clean prior to use. I do wish they weren't quite so expensive.
