Yeah that stuff looks good, but more expensive on a per clean basis!
if I were to do that on a regular basis the cost of cleaning the sensor would be close to my mortgage!
good for travelling again, and use on the road if the need were to arise.
Cleaning the sensor at home before an air travel trip would be best advised.
I may get a kit one day if it's as effective(at 100% removal) as wet cleaning is.
