Can believe this

Hmmm can't see this working, hmmmm looks intresting

I can believe that someone would make such a device, but I can't believe anyone with any sense would use it. Any air sucked through that thing would have to be replaced with equally dusty room air leaking in from somewhere.

But notice that it has filters on the front, so the intention is that incomming air should go through this device before entering the body.

If it works? Hard to say, since dust electrostatically bound to the mirror will probably not move. It's easier to force movement of dust with high pressure than with low pressure. And the device seemed very quite, so it can't have pumped any bigger amounts of air.

I have a feeling this was released on April 1st...

Here's another link.. http://xjrumo.com/2014​/08/05/cuifeng/ It seems that it has just been released and only in China.

But, it's gotta be good.. It's got a red ring around it

Looks more like a red her-ring.

I used to try using a vacuum cleaner once on my 400D, after vacuuming, the sensor dust doubled.

I like HP air for moving dust! I find that a 300 bar dive cylinder with a microbore hose is great for shifting the dust from older PC tower units .

These have been discussed on other forums and the consensus was that it's nonsense.

Another worthless gimmick to fleece money from the unsuspecting.
