it is a product that I had used for my previous SLR, so buy eyes closed. it is a multilayer protection which does not spoil anything in the quality of the 7D screen (or any other SLR with the corresponding model).
easy installation, no need to be an expert, just make sure the screen is clean before placing the guard!
And the end result is that we do not even notice that the screen is protected, because the product is well with husband SLR.
