Very good quality , the air blower easily removes debris and the lenspen makes my Canon lenses look like new

perfect for cleaning the viewfinder sensor of cameras, also to remove dust from the internal sensor and all the equipment, to clean the declaration of my imac etc.I'm recommended!

I feel that this is too expensive for what it is. Considering that the blower is unfiltered and the pen is a consumable, you would have to replace it every hundred uses or so. I found that cleaning the lens with the pens is an exercise in heightening anxiety and was not confident at all about maintaining the lens pristine.I was very afraid of causing micro scratches. I don't know if I was applying enough pressure or even the right amount of pressure, there is no indicator to tell you. If they improved this product with a pressure indicator then the value would go higher.Maybe they could test different springs tensions and find a spring that once you push down on the pen it can then show a red indicator through a transparent window on the side that tells you it's ... MoreI feel that this is too expensive for what it is.

I want to REMOVE debris from my lens, not deposit more on it!!!Low quality product for the price.
