I use it. My Photon came with Anycubic's Photon slicer which actually does a decent job but one thing I noticed was that when breaking off supports I was often left with gouges in the print where the supports attached. Not the slicer's fault, its more me being heavy-handed when removing supports. Chitubox addresses this cleverly by allowing the user to add a ball at the end of each support stalk. This leaves little bumps where the supports attached but resin is super easy to sand so its no problem. And gouges are a thing of the past. Supports are very customisable. Chitubox also allows the user to hollow out the model to a desired thickness and add drainage holes. And it adds the 'holes' as a separate models so you can use it to fill the holes after printing. Chitubox also lets you set up profiles for different printers, resins, layer heights, etc. So settings that work can be stored for later use.
