Never had that issue though I used the case and only had the probe for a month or so before the iQ+ came out and butterfly let me trade out my unit for the new one. The new model has a different cord probe interface. Cords are now replaceable. Not sure if that will make a difference or not. How is the lumify immune from similar cord issues? They use thicker plastics in their cord?
Last I saw the lumify probe was around $8k and data storage was over $2k per year if you signed up for a year (a little cheaper if you agreed to more months). Total cost to own of the lumify over 5 years was about $17,000. Butterfly storage would cost you around $2k over that time so you could buy 7 butterfly probes in your first 5 years and still come out ahead financially. Though butterfly recently had lifetime cloud storage for $999 for new users who bought a probe. I thought I was getting a great deal before they ran that promo when I got 6 months of cloud storage free lol
