Dear Logitech Support,
I’m writing to seek assistance regarding an issue I’m experiencing with my Logitech MX Master mouse, specifically related to the roller.

Whenever I use the roller on this mouse, I feel an itchy or tingling sensation on my fingertips. I’m unsure if this is due to the material, the design, or the internal mechanism of the roller, but I wanted to reach out to understand more about the potential causes.

Here are a few possibilities I’ve considered:

Could there be a material like nickel or another metal used in the roller that might trigger a skin reaction, such as an allergy?
Does the magnetic system used for the roller’s smooth scrolling function emit electromagnetic fields that might cause sensitivity or discomfort in some users?
Could there be sharp or unfinished edges on the roller that might be causing physical irritation?
I would greatly appreciate any information you could provide about the materials used in the roller and whether others have reported similar issues. Any advice on how to address or mitigate this sensation would be very helpful as well.

Thank you for your time, and I look forward to hearing from you soon.
Best regards,
Ali Akbari
