Model overview based on user reviews
The Defender sTarx GM-390L is a budget-friendly gaming mouse that offers a stylish design and customizable RGB lighting. It features seven buttons, including programmable options, and a DPI adjustment range from 1200 to 3200. Users appreciate its futuristic design and the ability to adjust the weight with removable weights, although some find it heavy. The mouse has a braided cable for durability, but the cord can be cumbersome without a cable grip. While the mouse is praised for its good response and durability, several users report issues with the sensor and scroll wheel over time, noting that the sensor can lose track and the wheel may malfunction. The metal legs provide smooth glide but can scratch surfaces. Overall, it's a decent choice for short-term use or as a secondary option, but may not be ideal for long-term gaming due to potential durability issues.

A controversial model. The appearance is decent, it has removable weights for weight adjustment, pleasant lighting, and perhaps its main advantage is its very low price. If you need something in the short term and plan to save for a better option in a couple of months, it's an option to consider. But I wouldn't recommend it for long-term use, as after a couple of months, the wheel starts working slightly worse than terribly. When scrolling down, it scrolls up and vice versa, no matter how you turn it, it scrolls chaotically. Also, from the very first days, I noticed it has a terrible sensor, it loses track from quite a distance from the mat as if it were a laser mouse. If you need a mouse for flicking or making 180-degree maneuvers, better save your nerves and avoid this purchase. Oh yes, I almost forgot, the cord... The cord pulls the mouse a lot if it hangs off the other side of the table. If you don't have a cable grip or aren't ready to improvise one, be prepared for your gun to pull along the mouse cord when it recoils. As for the programmable button, which by default works like a left-click cycling button, it's quite conveniently located, but there's one "but" that undermines the usability of the button – it doesn’t work when the right-click is held down, and why would you fire single shots from a gun when you're not aiming? Price, appearance, lighting Disgusting sensor, heavy hard wire, mediocre mouse wheel quality use Defender sTarx GM-390L few months |
The review is written after the mouse stopped working, but I am going to buy the same mouse because it is worth its money. The mouse is back in action after a night! Size and shape, two additional buttons on the left side of the mouse, a third button on the same left side that spams LMB, weight adjustment (Honestly, I haven't needed it in a year and a half), DPI adjustment (Used it a couple of times), and of course, lighting. After about 2 months, the scroll wheel became almost impossible to rotate; closer to a year of use, the mouse could simply stop recognizing movements, although the lighting worked, which was resolved by reinserting the wire; after a year and a half, the LMB stopped clicking, and the wire just absolutely refused to work in any way.  Sergey: use Defender sTarx GM-390L more than year |
I bought it on Goods.ru, it was delivered quite quickly. Futuristic design., patterns on the body., backlighting., possibility to customize each button separately., I was skeptical about the weight change, but it is noticeable., braided cable., excellent response (although it depends on how it is adjusted) After a month, the mouse began to creak, not much, but still., if you scroll the wheel away from you, it's fine, but if towards you, a crackling sound is immediately heard., due to the metal plate on the bottom of the mouse, the table gets scratched with a characteristic ear-piercing squeak., the backlighting cannot be changed (leave only one color, or program a specific combination)., the weight can be adjusted by just a few hundred grams., Denis: use Defender sTarx GM-390L few months |

Universal Soldier
Defender sTarx GM-390L is a low-cost gaming mouse without strict binding to any particular gaming genre. Complete weights allow you to easily adjust the weight of the manipulator: lighter for RTS strategies and MOBAs, or heavier for shooters. In the first case, the high speed of moving the cursor from one edge of the screen to another is important, and in the second, the ability to abruptly stop the mouse for precise aiming.
Strictly for righties
The shape of the sTarx GM-390L is slightly asymmetric, for the right hand, with stops for the thumb and little finger, so that the hand is less tired. Lefties can theoretically use this mouse, but it's not recommended, they'd still be better off choosing a fully symmetrical model. The cover of the case is made of grippy soft-touch plastic. All this is complemented by a colorful iridescent RGB backlight.
Perfect glide
Especially for those who complain about quickly erasable plastic mouse legs, the sTarx GM-390L has them made of metal, that is, they are as durable as possible and slide well. The resolution of the optical sensor can be adjusted with a pair of dedicated keys from 800 to 3200 DPI. The Defender sTarx GM-390L cable is fabric-braided and with reliable kink protection at the point of attachment to the mouse.
Macros for victory
On the right are three additional keys, on the left — one more. On all of them, through the Defender Game Centre application, you can bind macros, that is, quickly performed sequences of actions in games, for example, the procast of several spells in order. The Fire software function deserves special attention, it allows you to programme one of the keys to shoot single shots to reduce spread.
