KiCA Jet Fan 2 Electric Air Duster USED TO DUST OFF OPTICS - Has A brushless high-speed DC motor

I use a large Giotto Rocket Air Blaster($20). This tool looks good but cost is prohibitive for me. I don't think I would use it to clean my camera sensor though.

If you hold it away from the lens on the low setting it is a gentle breeze no more than a bulb blower.

I have two constructive comments my A-P brother..1 is more semantics, Wouldn't it be 2 speed blower not variable as in the speed of the blowing, varies in intensity? The second is more experiential... from both my photography and astronomy education, I learned never to blow air into optics from above - always from below. Pushing air from above can and will push dust into the corners of your optics, embedding it forever into the edges where it can be ground in when removing a cover or cell. The hard to work blower does make the job harder but also can never force dust or dirt into the edges - especially when used in conjunction with a light brush. That's why many hand pump blowers come with a brush top. Your thoughts on my comments? Always willing to engage in a meaningful dialogue. You've had so much to share where I've learned as well. Thank you!

@guzzialfa Hello! Good to hear from you. Not sure on first point? Great point on the use of the blower. When changing camera lenses I always try to put the camera body facing down as to minimize dirt/dust from falling in. Sometimes that isn't possible. When using the bulb type blower or this electric one I will start doing that. Always good to be cautious. I must say I haven't done that but will start. Appreciate your input, always something to learn. Clear skies my friend.

Tony, would you use it on your telescope optics?

Gary - I would have no issue with using this on all my optics. As stated in the video the wide tip and the lowest setting is what I use. Could even use it without any nozzle. On the AP forum a Kent Gittings stated the following about my video: "You don't really want a high speed air duster for optics. The only thing that can really scratch optical coatings is a crystalline substance, which is commonly sand. And guess what happens when you accelerate sand to higher velocity. You want low velocity dusters which is why photo shops when they were still around sold those little air bulb squeeze dusters or static camel hair brushes. And you don't use canned air due to the accelerant than can get on the optics if you shake the can. Just because someone says they have a great product doesn't mean they know anything about what they are talking about." I TAKE EXTREME UMBRIDGE TO THIS LAST STATEMENT HE MADE. I am not going to damage my optics. Again, use the low speed / velocity as stated in my video. I have never used canned air. I have lots of expensive optics and take EXTREME care of them. My optics do not get anything but dust on them. Not sure how sand or actual dirt from the ground would get on my optics. I live in the country and when the farmers are harvesting crop I will not use my scopes. You can see the dust/dirt in the air when the wind is coming to my direction. Hope this helps.

Tony, thanks for the thorough response. I follow your videos and trust your judgement. I did read Kent’s thread on the AP forum, not sure I fully agree with him.
