Nice that this is available! Are the chemicals by Fuji, Champion, Kodak, or ?
Separate bleach and fix are a must IMNSHO, for C41.
All said and done it's not the cheapest way to get these chemicals, but it may be more convenient for some who don't use larger quantities. Me, I go through about 5L in 3-4 days if I am backlogged with film to process.
Kudos for bringing this to market.
