Never tried that one but have used other lenspens with good result for telescope eyepieces.

First time a hear about it.

I use the dust-wand kit.  Excellent results.

DUST-WAND KIT for DSLR Sensor Filter Cleaning

I do use sensor swabs but thought this might be a good way to get rid of an annoying blob quickly.  Tried dust aid but I ended up with more mess on my sensor and the stubborn blobs remained.

Have the Copperhill kit with the pec pads and the modified spatula. Dust-wand is essentially the same products, except the spatula is almost the full width of the sensor.

Rocket blower, hold the camera back facing down, blow out dust, before going into cleaning mode. (who knows if it does anything but make me feel good?) Set to clean mode, blow it a couple of times.

Same process, one time each side of the 5c pad, throw it away. Just that a full width will cover the whole center of the sensor each time. The fluid is probably the same. I don't have a clip, I use Scotch tape.

I've seen guys who start the day, every day, with a sealed disposable swab of some sort.

All very interesting ! 

So far I've tended to use just the blower, as opinions seem to suggest 'Leave well alone', but the day will come when that stubborn speck refuses to be blown away !  Then what !? 

Very informative, thank you
