My remarks on the product,
- While already 4 to 28 sticks photography ok it's not cheap but then there is abuse (so yes they are designed in a sterile environment, blah blah blah) ... 28
-I Had beautiful miles take precautions and take me four times ... (yes the 4 sticks) sensor is not my own ...
For me the sticks are too wet and leaves traces (Thanks Product "eclipse")
To sum up:
I'm not armed and although I létais in 4 tests one should've run.
A beautiful packaging a good communication about a product are not everything and especially the money!
I do not recommend this product if like me you need to clean your sensor, choose the more expensive option of stick and dry the product at hand to manage the amount or even better go see a photographer!
