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.

Popular Mouse Comparisons
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.

Test Results
This mouse has a black, anodized magnesium alloy body with an exoskeleton-like framework on the top that extends from the bottom of the left-and right-click buttons onto the back half of the mouse. The scroll wheel is made of metal and has a lighter gunmetal color. The word 'Razer' is written on the left-click button, and a written slogan: "For Gamers by Gamers' is visible inside the exoskeleton body towards the mouse's heel.
This mouse doesn't have any RGB lighting zones, but there's a small LED light inside the mouse that flashes a color when switching between CPI settings.
This mouse shares virtually the same dimensions as the original Razer Viper Mini. It's approximately 1mm smaller in overall length and width, but the two shapes feel identical in hand.
This mouse has outstanding build quality. The top shell is made of magnesium alloy and feels sturdy in hand, and the bottom plate is solid plastic. The top shell doesn't flex or make any creaking noises, even with considerable pressure applied. The left- and right-click buttons have minimal side-to-side travel, but there aren't any grinding or alignment issues and no issues present when using the mouse as intended. There's some minor flexibility on the plastic bottom plate where the label sticker is placed, but once more, this is minor and doesn't impact normal use.
This mouse is remarkably lightweight in its default configuration, with a marginal front-heavy weight distribution. It's approximately 10 grams lighter than the original Razer Viper Mini.
If used, the adhesive grip tape included in the box will add a couple of grams to the total weight.
If you're interested in a wireless gaming mouse that's even more lightweight with a similar size and shape, check out our review of the Finalmouse UltralightX, the Finalmouse UltralightX Competition, or the WLmouse Beast X.
This mouse has a low-profile, symmetrical shape with two side buttons on the left and is virtually identical in dimensions to the original Razer Viper Mini. Much like its predecessor, this mouse is best suited for small or medium-sized hands and ideal for a fingertip grip.
