Finalmouse UltralightX Frostlord Wireless Gaming Mouse
Available Sizes: Small, Medium, Classic
Frostkey is included!
The lightest, fastest, most responsive wireless gaming mouse in the world. Period.
Presenting the UltralightX Frostlord. The last ULX. A limited edition final chapter of Finalmouse's Third Age.
With cutting edge 8000Hz wireless tech capable of 344 microsecond click latency, and 444 microsecond motion latency... the Carbon Fiber Composite ULX Frostlord is the benchmark for performance eSports mice.
Specially formulated frost white color was developed exclusively for the ULX Frostlord. With the paint protected by our new ULX competition UV matte top coat. Providing excellent grip and durability.
The sides of the chassis features artwork applied in a new undercoat process developed for our 10th anniversary mice. A hand drawn Frostlord finished in a stunning glossy white on white coating commemorates the last of the ULX generation.
The UltralightX Frostlord is an engineering marvel 10 years in the making.
You've never felt anything like it before. At only 33 grams the ULX weighs less than the amount of sugar in a can of Coke. For another reference; that's less than the weight of 1 Strawberry.
