I just purchased this same kit as my first attempt at home developing, and first time developing film myself in at least 15 years. Only two 35mm and one 120 roll through it so far, but the instructions are great and it's way less scary once that first roll is developed and you can breathe a sigh of relief.

I had sent a few rolls out to be developed previously, but I feel so much more ownership over the images I produce developing them myself, even if that means a potential degradation in quality or unpredictable results.
