As I hinted above at the alternative of using a Agfa Rondinax-60:
I just had a look at a Rondinax-35, out of me old stuff collection. This one resembles in its basic construction the type 60.
-) the plastification of the pull-ribbon has hardened and fractured
(easy to replace by nylon-filament or -ribbon)
-) the rubber O-ring, sealing the reel-axle, has hardened and fractured
-) the stem of the thermometer is stuck at 35°C
(most probably the glass tube has broken due to overheating of the stem with the black tank sitting in the sun in open box)
-) I did not check the thermometer sealing
So, expect problems when acquiring a Rondinax. For 35mm use there is the modern Jobo daylight loading tank, resembling their current tank system.
For travelling, with no means on improvising on a darkened room, I don't see the advantage at all of these tanks, as who is able to take films, tank, beakers etc. with him, should be able to add a changing bag.
I rather see the advantage (if at all) rather in Easy-Loading than in Daylight-Loading. I also have people with manual disabilities in mind.
I think the designations of these tanks are erroneous from a marketing point of view.
