It's great! I often wonder why more people don't use it. It's all I use now. Simple, idiot proof and wonderful results. I've tried a lot of developers over the years and after I started using Diafine, I tossed out all of my Microdol, Rodinal, TEC, T-Max, Technidol and D-76. I even use it for Tech Pan.(posted 8386 days ago)
