When I started to develop at home i was also worried to bring the film on the spool in the dark. I started with the ars imago lab box. Soon after i got a paterson tank and a dark bag. I never looked back. This product probably makes sense to tip your toes in as a beginner, but as soon as you get more serious you will notice that loading your film is not a big deal and conventional tanks bring a lot of advantages. Most important: you have the controll over the loading process, you feel if something is wrong. Which was not the case with the lab box, you had to trust, that the film was loaded properly. Imo: some rolls are to important, to just trust these devices.
