The Razer Viper Mini Signature Edition is a lightweight, wireless gaming mouse in Razer's Viper lineup. This mouse shares the same shape as the original Razer Viper Mini but has an exposed exoskeleton design with a top shell made of magnesium alloy that Razer advertises provides the best strength-to-weight ratio compared to plastic and carbon fiber. Under the hood, this mouse uses similar high-end internals to other recent Razer flagship releases, including a Razer Focus Pro 30K sensor and Gen-3 optical switches. Additionally, this mouse comes with a Razer HyperSpeed Dongle that is unique to the Viper Mini Signature Edition. This dongle allows you to set a maximum wireless polling rate of 8000Hz, and it's the first wireless gaming mouse on the market to offer this feature.
This mouse was originally released exclusively on Razer's website and select physical Razer stores as a limited quantity drop. Razer has committed to continued production in batch drops according to demand, but as of the writing of this review, it's currently out of stock.
The Razer Viper Mini Signature Edition is decent for office work but isn't designed specifically for this use. That said, it has outstanding build quality, and you can reprogram any of the buttons using the customization software. This mouse is best suited for small or medium-sized hands but may be less comfortable if you hold the mouse with your palm in contact with the exposed exoskeleton framework on the back of the mouse.

The Razer Viper Mini Signature Edition shares virtually the same shape as the original Razer Viper Mini but is fundamentally different in most other ways. In contrast, the original Viper Mini is a wired gaming mouse between a mid-range or budget price point. However, the Razer Viper Mini Signature Edition is considerably more expensive than most gaming mice, including Razer's current flagships. This mouse is the first Razer mouse with a magnesium alloy exoskeleton body and the first commercially available gaming mouse to support a maximum wireless polling rate of 8000Hz.
This mouse bears conceptual similarities with the mice in the Finalmouse Starlight lineup and weighs virtually the same as medium-size variants, like the Finalmouse Starlight Pro Tenz Medium. The Razer Viper Mini Signature Edition also uses the same top-of-the-line sensor as recent Razer flagships, like the Razer Viper V2 Pro and the Razer DeathAdder V3 Pro. However, the Viper Mini Signature Edition surpasses these mice in terms of overall performance, thanks in part to its wireless maximum polling rate of 8000Hz, which provides more consistent and marginally better latency and sensor performance. Although, using the maximum polling rate of 8000Hz also comes at a significant cost in terms of battery life and required CPU processing power. While this mouse delivers exceptional wireless gaming performance, it also carries a significantly higher price tag than most premium wireless gaming mice. Razer has stated that it plans to release this mouse in small, irregular batch drops, so it may be difficult to find available, depending on when you're reading this.
