Keeps my holosun optics nice and clean!

Love the aluminum body, both brush ends are of very high quality… Simply a must have item, don’t hesitate

Overall the brush assembly works well for my occasional usage.

Perfect

I have used various types, models, and sizes of this and I love them. I use it to clean all of my photo gear and glass. I also use it to clean my camera sensor with NO difficulty or problems. I take it with me on trips since if your gear is dirty, you can't thoroughly clean without this if you don't pack it.

Works great

The lens/sensor cleaning tip is the same as every other brand out there. I used this to clean the glass on pistol red dot optics. Just like every other optics cleaning pen it is never a good fit to clean the entire glass of the optic lense, especially the inside. Also, make 100% sure the glass has no debris of any sort unless you want to make the cleaning process 4x longer, or at worst scratch the glass. I also. Suggest getting a good coated glass/lens spray to really get it crystal clear. My steps for cleaning are, first I used compressed air to blow away any debris on both sides if the glass, then I spray both sides of the glass and wipe clean with an appropriate microfiber cloth (not all are created equal), then I use the pen to try and get any spots I missed with the microfiber cloth. If you get the pen tip wet, prepare for a nightmare of trying to clean a bunch of new smudges or haze on the glass. Nothing impressive or terrible about the product. If you have some sort of lens/sensor/glass cleaning pen already just stick with that.

Convenient and efficient. Great for a quick clean of lenses during shoots.
