Jobo is next to Paterson, and Kaiser Kindermann most common brand, which Darkroom Accessories concerns. Unfortunately, the brand, like so many of the analog time, victims of the digital "turns". The Jobo but still does its thing, and indeed very good. The 1520s tank has to be able to two 35mm or 120 roll films develop a volume of 500ml, making it large enough this time simultaneously. the lid closes tired, the light trap is very effective and above all easy to use in the dark (in contrast to Paterson). The tank is part of a complete system that can be expanded modularly. From Rotieruntersatz, on volume expansions or Spülaufsätzen will not miss anything. You just have to be lucky enough to find remainders, because new it is no longer produced. In addition, development of coils, can not be used in other tanks because of the different Filling cylinder, which are the light barrier at the same time. So one should not be system will compile all at once but gradually, one is at Jobo probably somewhat riskier way and Paterson or in Europe especially emperors since probably the safer banks, though of course not said is that these brands still forever exist. Therefore only 3 stars
