First, a praise for the fast delivery and good packaging. The films are not exactly what I expected. There are 6 films in a highly tight welded bag. This one gets only with scissors and is a danger to hurt the film. Second, the films are so highly charged that they attract every speck of dust in the room literally magnetic. Here is my advice to all the slides really as indicated on the package, install it in a very clean room (bathroom without pompoms). To my shame I must confess that I have used up all six films and each time always bubbles or micro dust was included, even though I had painstakingly made sure that the tablet before dust (Brillenputztuch) and was clinically clean. However pasted as already mentioned every time a speck of dust in the exact center underneath. Even I can do to give the equipment to the camera to remove because it pushes also like under the film during application. All in all it went well here the letze film. Unfortunately, there had been no films from other manufacturers, and I had to buy this .... So what ... okay for the price ....
