These protective films fit perfectly on my EOS 600D. They are very transparent, so asked. It is not easy to take one of those films without air bubbles, however, the bubbles are not visible when the screen on. Protection side, it is undeniable that protects well from dust screen, possible projection, stripes and so on ... Personally received very quickly (before the scheduled date), I was very impressed with the responsiveness and speed of this British seller. I also used these films for a 450D (also 3 inches), for which I slightly recut. I do not regret this purchase (especially considering the price!) And I recommend to all holders 600D and earlier models. (I disagree for 650D)
