Today I picked up the images and the results are really great. As I again explicitly written on the cameras that they must be operated with lightning necessarily (the wedding took place in it) have become consistently good images.
In Detail:
Of the 27 frames per film have been developed depending 23-27 photos. The rest was probably underexposed (which does not necessarily lie on the camera, may indeed have been an operating error). These images have become really great with a few exceptions, certainly no SLR quality, but that one can not expect. Not a single picture is really blurred, the flash is sometimes a bit garish, but all in all the pictures turned out really great. For our purposes - a few snapshots of the Hocheit from which you can then make a nice album for the couple - is the quality of the cameras and the images really been more than adequate.
And on the subject of development: I have let go at the drugstore with the two letters, has a total cost for the 20 cameras in real good quality 45, ie slightly more than 2 per camera. No disposal costs for disposable camera, nothing. The cheapest picture costs 5ct, the development rate per camera is 95ct.
All in all I can recommend the cameras without restrictions, the operation is totally easy, it makes everyone a lot of fun and the pictures that got out, are really great. Therefore really !! a very clear recommendation
