Title: Extremely useful product!
Review: If you have dust in your DSLR camera, then go ahead and buy this! It works like magic. Just remember that if you have dust on your sensor, then you're going to have to turn the camera on, put it on BULB mode and then press AND HOLD the shutter (so you can access the sensor) and at the same time use this blaster in order to get the dust off the sensor.
