Has anyone used Ars-Imago monobath for processing ?

Hello all,
Has anyone used Ars-Imago monobath for processing Black and white film ? In the near future I am going to start processing my own films and thought I would give this a go to start with. How many films can I process with it ? As it has a a two week shelf life after being mixed my idea was to build a small stock of used film and then process in a batch.

Thanks all

Just thought I'd bump this unanswered question...

I can't say I've used ARS-IMAGO monobath, but I have used the R5 monobath from New55. It is simple to use, temperature is critical, but I found it too expensive compared to traditional chemicals like D-76(Arista 76 and Arifix).
