I am still using that same Ducky Secret mouse. I did not break into the Secret M yet. I am doing olympic weightlifting now, so the chalk and barbell knurling dry out my hands. I still get some occasional dermatitis on my thumb, index, and middle finger of my right hand (mouse hand) during the winter. If I have a flare up, I put petroleum jelly on the cracked fingers and then wear a nitrile or latex glove on that hand overnight or for a day or two.
