+1. Follow their instructions, particularly with regard to contamination of A with B (don't), minimum time and agitation (agitate gently and don't over do it) and it really is very easy. You might or might not like the results, but if it sounds interesting to you it's worth a try. With its relative insensitivity to time and temperature as long as the minimum times and wide temperature range are complied with it's a lot easier in most ways than single bath developers.
