A big part of my dislike for this is that this isn't going to teach anyone how photography "used to work" or anything like that. It's a toy.
I work in a darkroom, I have a lot of experience processing film by hand and making prints. I know a bit about it.
This seriously looks designed by someone who has never spent more than two hours in a darkroom. Encouraging people to set up tiny darkrooms in closets or wherever they can with trays of open chemistry, is a bit irresponsible.
Here's the MSDS for Ilford Multigrade, the developer they recommend: http://www.ilfordphoto.com/Webfiles/2007117133512849.pdf
And for the Rapid Fix:

It's not super dangerous stuff, but you still need to take some reasonable precautions with it.
And that tray rack? Anyone who has ever worked in a darkroom would never think of stacking trays like that. You need to pick up the print from the chemistry and let the excess drip off before moving to the next tray--this setup is going to be having people spilling photo chemistry all over the place, in a room with no ventilation. Smart.
All the text on the indiegogo site just sets off my rage. Everything at Ilford is not "vintage technology", they have been churning out new products for years. And this? "Old school print development makes every print slightly different, due to microscopic imperfections in the silver halide coating on paper and the chemical reaction that turns parts of the coating black or grey." This is just plain wrong.
This isn't preserving analogue photography. It's trying to sell the idea of being a darkroom. The indiegogo has lots of text about red light bulbs (most darkrooms use amber lights, but I digress), prints hanging on a line, the smell of chemicals, but almost no examples of what the prints made with this thing look like. Why? Because that's not the point.
