And, yes, Diafine is very easy to use. The only thing you really have to worry about is to understand how you must expose your film to get the results you want, make sure the developer is within its temp range, and agitate well in both Bath A and B. Beyond that, there isn't much you need to do, other than making sure that your storage bottles are full. You may have to buy another kit and replenish Bath A, since it will slowly become depleted with each roll.
