This is a conclusion i make from the poor bottle seals together with the statement of very long shelf life. Normally this would be a contradiction, but i do not think they would jeopardize their reputation, and thus i draw that conclusion. So far it seem to hold up, both my opened concentrates and the working solutions have not shown any deterioration after 4 months in less than ideal storage.

The problem with these developer kits, as i see it, is the lack of deeper information and user experiences. The latter part is understandable since it is a new product, but the former should Rollei be criticized for. This was the reason for me to start this discussion in the first place and i hope that user experiences over time will make up for the lack of deeper information.
That's good to know...if I do end up keeping this kit, I hope it'll be useful.
