In the - very tight - no manual is further evidence for the handling of air bubbles. In the "other product details," the Amazon site I found today "to see If after assembly bubbles (No dust inclusions), these disappear after 24 hours without any help."
How well the (not) work, I have demonstrated on an uploaded image. I told my wife yesterday bestowed the camera for birthday and am attached equal the film (s). Tonight I've checked, and see (by 2.5 days) no improvement. The spots are just as visible in the display or not connected, the reading of the settings interfere significantly. I suspect that the film was deformed or marred because of their thickness and the force at Strip out - and I thought I was, however, strictly follow the instructions supplied.
The product is for me not only useless but even hinders the use of the camera - so we'll try another. Too bad about the money, and shame that the joy was so marred more than that special gift with it.
I would like to add that I successfully (finally bubbles) have been fitted in several films with practice, most recently with a 3.5 "and a 4" smartphone. Yes, the room was largely free of dust (bath shortly after showering), the display was hyper-clean and without any lint, and is definitely not to inclusions of foreign bodies.
