MANBASNAKEAJAZZ AJ139 PRO Wireless Gaming Mouse,Lightweight Computer Gaming Mice with PixArt PAW3395 Sensor,26,000 DPI,6 Programmable Buttons,1000Hz Polling-Black

I must admit it is a fantastic mouse IF you are looking for a chance to invest your limited budget into the best sensor but nothing else. The body feels genuine plastic and a bit cheap, the click is not enjoyable at all. Grab but hand slips immediately. And the battery might lasts only about half the length of a razer viper.BUT the sensor is indeed good. At the costs I mentioned above, you will get the smoooothest and most precise cursor movement at this price. So what else you can ask for?

Looks exactly like Logitech Pro X mouse.Moue is very light and comes with extra gliding pad. All the button works fine and like the click feel. Annoying back/forward button is well designed to avoid accidental thumb click. Ergonomic design. Charges quick and wireless connection is quick (no Bluetooth).One of the best mouse I ever used.Excellent value for Logitech one is about 2x more expensive.

TLDR: This is a great mouse, and somewhat of a disappointment as well, with one issue that really bugs me.The shape is fantastic, it reminds me of a mix between the full-size Razer Viper and the Logitech G Pro Wireless, or a G Pro Wireless without the rear hump. I never was a fan of the rear hump on the G Pro Wireless, so this suits me better. However, it isn't quite as flat/narrow as the Viper. The weight is great at only 59 grams. It has one of the best sensors on the market, and the wireless performance has been flawless for me in my testing. Inside the box you get a soft paracord USB-C charging cable, USB extender, and some extra mouse feet.However, unlike my AJ199, which had zero quality control issues, the AJ139 has very poor feeling clicks. My left click makes a loud popping sound every single time I click, and it is very distracting. It also slides sideways when you press down and the switch actuates, like it is rubbing on the switch instead of pressing down straight. The right click sounds better, but has a grinding feeling to it and also rattles occasionally. The scroll wheel feels great, and the side clicks have some pre-travel, but work fine. The middle click is great.In short, this mouse feels like it came so close to being perfect, but if they could make the main clicks feel better they would really have a winner on their hands. Sadly, it is too annoying/distracting for me to use as the clicks to me as just as important as the shape/weight.
