I posted this on another MF digital forum, but wanted to share here as well....
I can't recommend this product highly enough... I have been chasing dust on sensors for years and this does a ultra clean air blast without residues found in canned air. As most of us know usually a wet clean isn't needed.. just dust removal. Brushes can carry old dust and the traditional blowers just blow new dust as it pushes away the old. Cleaned my D700 in 30 seconds and P40+ in 20... not a speck in either LCC shot. Hope this helps some folks frustrated by the dust battle.
$31.74 shipped from KOH. .00165% the cost of a P40+ back... such a deal.
