Title: Not worth the risk
Review: For just a little more than the price of this product, you can have your sensor professionally cleaned by your local dealer. I made the mistake of deciding to do it myself and ended up with a scratched sensor filter thanks to a plastic burr on the very first swab I tried -- what awful quality control on a product meant to clean the most expensive part of an expensive camera body.
