Unfortunately, this is my first negative review of a Razer product. I have long wanted a large mat with customizable lighting, tossed between Razer and SteelSeries. On 10/28/21, a mat from Razer was ordered on the market from the seller 4FRAG. 11/16/21 took from the point of issue, there were delightful emotions from opening the products of this brand. The rug is pleasant to the touch, there is a Synapse program through which you can customize the backlight as you like (later I synchronized all the rest of the products, which I really like). First of all, I reduced the brightness of the rug to 15-30%. It was very bright and it hurt my eyes at night. Gradually began to be completely ated for this company (mouse, keyboard, headphones). In March 2023, I noticed that the keyboard and mouse dock shine much brighter than the mouse pad, turned the brightness up to 100%, nothing changed, except for the backlight near the backlight adapter, where the brightness changes. Unfortunately, the warranty for the rug is 1 year, so a year later I was left with just a large rug with a bright left corner and a biting fishing line for 5k. P. S. 3-5 photos were taken at night, it seems that the mat is shining and I'm talking some nonsense, but just look at the brightness in the left corner of the mat and the glow of the docking station and keyboard. From their brightness, the phone catches "glare", or completely interrupts the light from the rug. In reality, I donโt see such a glow from the rug, only on the camera. 1-2 photos were taken in a brighter time and here we can already see that there is light only near the adapter in the left corner of the rug and the light from the rest of the periphery is also interrupted. It's a pity for this mat. it was with him that my acquaintance with this company began and, unfortunately, only she disappointed with this marriage. P. I found only one similar review on this rug with the same marriage, only that rug went out earlier and they were able to exchange it, I didnโt get such a chance)
