That being said, today we’ll be talking about the A4Tech Bloody A70 Activated Ultra Core 4 mouse. As mice are one of the most crucial parts of PC gaming, it’s great to see more companies taking interest in gaming peripherals.

We previously reviewed Patriot Viper V570, ROG Pugio Gaming mouse, Gladius II, and Impact from Asus out of these mice the Gladius II stood on top due to its amazing shape and great customizability, winning the recommended award from our reviewers in the past. Now, let’s see if A4Tech Bloody A70 can score any of our awards.

I got a chance to review the A4Tech Bloody A70, an elegant looking mouse due to its neon multi-color backlit which you can adjust through software to best suit you and it has a good build quality which is quite impressive to me. The mouse has 8 buttons for in total. The neon multi-color backlit looks really elegant, which is the best thing about this mouse.
This mouse comes with a price-tag of $29.99 on Amazon at the time of review, which isn’t a lot for such a mouse.
