Redragon Wireless Gaming Mouse, 54G Lightweight, Tri-Mode 2.4G/USB C Wired/Bluetooth, Black PC Gaming Mice for Computer Laptop Mac Windows, Max 128000 DPI, 1K Polling, 6 Programmable Buttons, M821

Yet another excellent budget lightweight tri-mode gaming mouse from Redragon
I have always been impressed with Redragon mice and the software that comes with them, and they seem to constantly come out with new models. This one is another of their lightweight gaming mice and unless you need really high DPI or a polling rate higher than 1000 Hz, this mouse might be for you.The Redragon M821 comes in their typically large red box with stickers but the high quality braided USB-A to USB-C cable I got used to getting with their gaming mice comes instead with a thinner rubber cable with this mouse. The 8 page user manual all in English is decent sized and easy to read. It’s also much better than the multi language pdf file you can download by scanning the code on the front of the manual. The easiest way to find the driver software is not by searching through all the various Redragon websites, but instead by simply doing a search for “Redragon M821” where you will find the download link for the software near the top of the page you find at the top of your search results. It connects over the 2.4 GHz dongle, wired or over Bluetooth.The Redragon M821 weighs just 53.0g, and the design should be familiar to anyone who has had a lightweight Redragon mouse before, with the DPI button and light on the bottom of the mouse. The logo on top is a very subtle shiny black which does not call attention to itself.Buttons and Ergonomics: The mouse is suited for left or right-handed use only, and is very comfortable to hold. Because it is so light it is effortless to use. The mouse skates on the bottom work well, but you need to remove the thin clear covering that cover the mouse skates on the bottom first. The left and right clicks are not 100% silent, but they are quiet as mouse clicks go. The mouse wheel is one of the very best I have used, and the mouse wheel button does not require very much effort to push. The forward and back buttons are also fairly quiet and work well. The forward button has tiny bumps on it making it easy to tell apart from the back button and I’m very happy Redragon continued with these buttons for the forward and back buttons as they are still my favorites.Battery: 400 mAh which they say is good for up to 70 hours of use in BT mode with a recharge to full time of 2 hours.Driver software: You get up to 3 profiles you can set up. You can have up to 5 DPI levels, with the default being 400-Red / 800-Blue / 1600-Green / 2400-Cyan / 3200-Purple (Up to 12800 in the software) and each DPI level can be changed as you like along with whatever color you prefer for that level. GROK AI calls the S205 sensor in the M821 with its top 12800 DPI “ample for 99% of gamers”. You can also change the report level to 125Hz, 250Hz, 500Hz or 1000Hz. Another tab is the Macro tab which I did not try but I assume it works. Unfortunately, there is no battery level indicator in the software which I think is a major omission, although the battery level does display if you use it in Bluetooth mode. The LED light flashes red when the battery is low and needs charging, but you need to turn the mouse over to see it. The DPI returns to the default DPI level light when the battery is full.Sleep mode The default sleep mode is either 2 minutes (manual) or 10 minutes (listing). However, the sleep mode an be set to 3, 5 or 10 minutes or turned off completely in the software. You need to click a button to wake it up from deep sleep mode.(The DPI levels as well as the report rate can be changed without using the software by following instructions in the user manual.)Redragon M821 – $29.99 ($26.99 with 10% discount and $21.59 with $5.40 off coupon)Size/Shape: 4.8 x 2.6 x 1.5 inches5 DPI levels: 400-Red / 800-Blue / 1600-Green / 2400-Cyan / 3200-Purple (Up to 12800 in the software)4 polling rates 125Hz, 250Hz, 500Hz, 1000HzWeight: 53.0gBattery: 400 mAh1 year warrantyPros: Good software, quality mouse skates, lightweight, quiet mouse clicks, 5 DPI levels, 4 polling rates, ergonomic and comfortable to use for long periods, smooth easy to use mouse wheel, has storage compartment for 2.4G receiver in the bottom of the mouseCons: Driver software lacks battery level indicatorHard core gamers may want more features, more complete software, a larger battery or a better sensor, but for the casual gamer or someone who just wants an ergonomic lightweight mouse for desktop use, it’s an outstanding mouse and an excellent value.

Great mouse at a fantastic price, battery is lacking though
I am very impressed with Redragon M821 mouse overall. It is very lightweight (weighs in at on 53g on the dot on my scale) and precise. It outperforms my 10 year old Steelseries by a mile. The buttons are not very loud but still have a satisfying click and feel responsive. I would have never expected performance like this from a mouse that is sub-$30.The mouse feels well built albeit a bit cheaper than more expensive mice I have tried. I prefer the simplicity of it personally. The mouse wheel and middle click are spot on for me. It feels a bit cheap but I have a feeling some of that is due to its lightweight. I don’t mind and think it feels great in my hand and is comfortable to use. The mouse skates are nice and it glides on my hard mousepad with ease.There is one drawback and it is pretty substantial; the battery life is nowhere near what is advertised. I am using the mouse in 2.4g mode and I am lucky to get 20hrs of use out of a full charge. This is substantially lower than the advertised 70hrs.Overall, this mouse is a killer super-budget mouse. I am impressed with its performance and comfortableness. The only drawback is the battery life. If I was able to get even twice as much battery life out of it, I would say it is worthy of five-stars.
