I forgot to say it’s basically just boiling the parts for a certain number of minutes. They give you directions and a mat to dry the pieces on so if you are organized with meal prep it’s not a big deal. I was part of a trial and had a nurse walk me through it all at first over the phone (zoom). I’m 75 and it’s hard to teach an old dog new tricks, but I did just fine with one lesson. I don’t think they even do that now. I’m a visual person so it was helpful. Irene5
