Awesome sensor cleaning solution for travel. So much better thn having to carry around sensor swabs and eclipse cleaning solution. Its gets rid of 98% of the dust that's visible on the sensor. There's some stubborn ones that just won't come off without a liquid solution. Easily carried in my camera bag.
I used this to clean off a good bit of dust and fibers from the sensor filter and it worked great. I like the case it comes in although it makes it bulky for travel. But, how well the product works makes up for that. I plan on using it at least monthly just as a precaution.
I don't know why I didn't think of this!
I saw the spinning Sensor brush Arctic butterfly at wppi and the Rep cleaned off my sensor with the conjunction of using sensor loupe 7x..it took about 1 minute to have my rebel sensor from a complete dust party to sparkling clean
While this does remove some dust, I would say this brush may move the dust from onside to another. If you have a dust problem I would recommend a wet cleaning method.
