Summary: Nothing else I've seen touches it for power, certainly not its sibling the Giottos CL2810 Q.Ball Air-Blower. It's always in my gadget bag and I use it when changing lenses -- to clean the back of lens going on, not into the mirror box let alone onto the sensor.
Summary: The Giotto Rocket Airblower is an excellent product if not a tad large. It removed all but the most stubborn dust from my 5D sensor and it's great for cleaning lens's, those little hard to get at areas on the camera and PC keyboards. All in all an excellent product!
