Title: Will kill your sensor.
Review: I bought one of this blasters like two years ago. The blaster it is not only left black residue in my hand, but it smeared the sensor with the same goop. So, after almost an hour doing a wet cleaning on the sensor the goop it is almost gone. Hope I have not scratched the sensor. It definitively do not work the risk. It will work for a year or two, but eventually will spray the sensor with decaying rubber.
