Not really. SensorKlear is simply a funny shaped lenspen with thicker sponge, from what I've read.
The cleaning kit uses some special plastic which literally uses its adhesive properties to remove dust. At least it feels adhesive when you clean the CCD with it. In a funny way, that is.
If you have used lenspen before, then the SensorKlear is just a glorified lenspen.. I've experimented with using a relatively less used normal lenspen to remove spots, it kinda works, but someone somewhere else pointed out that since you are just moving the lenspen around.. And you can't really clean it per se.. You should replace it after a few uses, if not you might be dragging abrasive dust which is left on the lenspen tip and.. Well, we all know what happens when you do that!
