Interesting! Apparently these are a reform of legacy offerings. Very cool.

I use their C-41 and E-6 Colortech kits. Their advertisements emphasize user friendly over any kind of resulting film characteristics. I'm a long shelf life, single-shot developer person and I like their idea. It can be both convenient and economical to not have to toss out development chemicals exhausted from age when you go through a period of inactivity of developing film.

I just read their instruction sheet by translation. A concern I have, if I'm reading this right, is that you are still making batch of working solution from the tablets that is good for more than the typical 80-160 square inches worth of film area from 1 or 2 rolls of 135-36 canister/120 roll of film.

If you only want to develop one roll of film, that means now have to store the working solution to optimize its capacity if you just made a batch. And once again you have developer aging while you wait to shoot and develop your next roll of film. In my humble opinion, that is not as convenient and user friendly as making one tablet develop say 1 roll of 135-36 canister or 120 roll film, single-shot.

But you can store it far longer than liquid concentrate...

And you can develop one to two films with one tablet.

I wasn't sure what the instructions were saying. To develop one roll of 120 film I need at least 450ml to cover the top of the reel in my tank. Their table says that takes 3 tablets and is good for 9 rolls of film.

Perhaps they have a magic tank which needs only 150 ml
