i have use the mouse pad for close to a year. around 8 months into use, i noticed the light intensity of the glow weakens. i didnt think much of it and simply increase the brightness under setting. now under max setting, only the small portion glows near the connector. 95% of the rest of the mat has almost no glow at all.

checking online gave me replies of many with same issue and seems theres no fix nor replacement for this. so it is normal and the lighting effect is basically one-off?

kindly advise.
