Hi, everyone! I've had my FR245M for a couple of weeks. This week I noticed very light surface scratches on the OHR. They are not cracks by any means (like the ones I've seen posted on these forums) and can't even be felt when I touch the OHR, but I've been super careful with it. I clean it everyday after my workout and make sure to carefully dry it.
From what I've seen online seems to be common and should not affect the sensors in any way but I just wanted input from the community to confirm it's something normal and that it can happen even if you are very careful with it.
I've attached a couple of pics. Thanks in advance!
