A4Tech Bloody J90 (1080478)
 | Outdated Product Bright, easy to use and functional gaming computer mouse, positioned by the manufacturer in the middle price range. The case has a symmetrical design, equally well suited to both right-handers and left-handers. The A4 Tech Bloody J90 has 11 buttons and a scroll wheel on board. At the same time, the buttons themselves are designed for operation in an intensive and highly loaded mode — the durability claimed by the manufacturer is about 20 million clicks, while the wheel is designed for 500,000 rotation cycles. The manipulator works on the basis of the optical sensor PixArt PMW3325 Gaming Engine. The sensor has a good resolution range: 100-5000 dpi, the USB bus polling rate is in the range of 125-1000 Hz, and the button response time is 1 ms. The maximum jerky acceleration at which the manip...ulator works adequately can reach 20G. Let's pay attention to the fact that the body of the manipulator has 15 backlight zones, the gradient of which provides for numerous shades. The base of the mouse is equipped with metal legs Metal X'Glide Armor Boot, which provide the effect of easy ironing on the working surface of literally any rug; while the working life of the legs is 300 km. Let's also pay attention to the fact that this model has a Bloody J95 modification, which received an asymmetric body designed for right-handers. |

I bought this mouse when my old one (wireless horseradish knows where) broke down, a very good mouse, I took it for my laptop, then I also bought bloody headphones Backlight, ability to customize additional buttons, number of buttons, cable length, quality, and much more (I can’t say because I’m not at home) The software sometimes does not start the first time use A4Tech Bloody J90 more than year |
Best for the money. Size. Shape. Number of buttons. Microswitches and sensor top. The appearance is beautiful. Suitable for left-handers and right-handers as it is symmetrical. Very functional. Easy to repair. Very fragile. If you tend to blow up, it's not for you.  Sozdatel Vsego: use A4Tech Bloody J90 more than year |
Beautiful and convenient mouse. A huge number of additional buttons. It comes with software from "Bloody," but it's super terrible both in terms of design and ease of use. The lighting is beautiful, but only in stock modes; the customization interface is awful. There are issues with the mouse wheel's rotation; it lacks precision and sometimes activates on its own if you don't spin it quite enough. Overall, for this price, the mouse is top-notch; if I had the opportunity to return it to the store and buy something else for this price, I would buy it again. The backlight feels right in the hand (the hand is not oily; the fingers are not long), PRICE, braided wire, the ability to program certain scripts on the buttons through the included software.

left handed gun
Gaming peripherals from A4 Tech have an interesting positioning. On the one hand, it does not pretend to be universal coolness and laurels as the favorite weapon of cybersportsmen. On the other hand, it costs not much cheaper than eminent competitors, causing a fair question, why then buy it at all? Usually, the combination of price and unusual features is the decisive factor. For example, the $30 Bloody J90 model offers potential buyers an excellent low-cost PixArt PMW3325 sensor and a unique symmetrical design that is equally suitable for right-handed and left-handed control.
7 additional buttons
In principle, such tricks are not uncommon for other game controllers, but with one caveat. Additional keys are always located on the left wall, so if you want to shoot from the left hand, be kind enough to do without them. A4 Tech did not skimp on auxiliary buttons: 2 on the left side, 2 on the right side and 3 more under the wheel. Given the possible number of combinations, it turns out to be a good alternative to keyboards with macros. Another question is that the mouse is far from the most ergonomic: the plastic on the sides and top is pleasant, the switches are responsive, and the balance is quite up to par, but it is quite heavy (153 grams) and, much worse, many of the decorative inserts scattered around the body are located directly under hand constantly distracting and annoying. If you decide to take it, then be sure to check this moment.
Original RGB lighting with 15 zones
Otherwise, this is a very successful inexpensive mouse, which in many respects outperforms low-cost gaming models from the same Logitech. For example, the sensor boasts a good resolution range: 100 – 5000 DPI, and the button response speed is 1 ms. The maximum jerky acceleration, at which the manipulator works adequately, can reach 20 G. The sensor behaves well up to peak performance, lags and motion artifacts, we could not detect. And the RGB lighting here is such that you can take it to Times Square: LEDs are literally scattered throughout the body, and there are already 15 backlight zones! It is a pity that the proprietary software is far from being as polished as that of Razer and SteelSeries, so the backlight settings are not as rich as they could be.
