Hi Susan.
Thank you for sharing your feedback and for being a loyal user of the system since 2021. We’re glad to hear the cold water distribution is working well for you.
Regarding the changes you mentioned—the thinner pad, stiffer material, and removal of the patella pad—these were updates made by the manufacturer, DonJoy, and we don’t have control over design changes. For more details or to share your feedback directly, we recommend reaching out to DonJoy, as they make the final decisions on product design.
We appreciate your input and hope your knee replacement pad continues to support your recovery.
