I have the LK Blue switches and they feel good. The keyboard itself feels pretty solid, although you can twist it if you try to. The metal faceplate is great, but the plastic sides and bottom is meh.The switches themselves feel good, with a satisfying click from each press and a noticeable bump as it comes down. They are a little soft for my tastes, but I'm sure that is easily changeable with some heavier springs. The RGB software is clunky and has a relatively steep learning curve when creating your own animations, but it works. I would like some more customization. For example, I love the mode that changes the key color when you press it. But, I want to change the base color and the color that the keys change to when pressed. The leds themselves don't seem to have a full range of colors (not as good as the Razer Chroma products, for example). There is a noticeable jump between each shade. You're not going to get 10+ shades of red. you're going to get maybe 3 shades and the 7 other shades are going to look identical to one of the 3 shades. They keycaps are fine if you like the font style, but it was too aggressive for my tastes. The stems of the switches seem to rattle in their housing, like if I take a keycap off I can wiggle the switch stem itself and hear a hollow plastic sound, but this obviously doesn't affect normal typing and is impossible to notice unless you're looking for it. The one things that I'm disappointed in is that the spacebar has a weird spacing of the outer two stems and makes it hard (maybe impossible?) to replace with normal keycap sets. Overall, would I buy this again? I I just wanted to be able to change colors to match my build, yeah, this is a great keyboard. If I wanted RGB madness with everything on rainbow, maybe fine something else. Is it worth $100 for what it is? Absolutely Review: Worked for 1 year... - It was my first optical mechanical keyboard, and it was really great. It was fast, and I loved the sound of the keys. But after only one year, one of the keys popped out (check the image), and there is no way to up it back to its original place. I tried glue, but it wasn't the same anymore and after 2 weeks it popped out again. It clearly states "Each key lasts over 100 million press" on their description page, and I don't think I reached that in one year. Atfer contacting Bloody's support based in USA, one of the customer service team member confirmed they would send a new one for me. It has been 4 months since that email, and no response from him even after a few more mails from me. I am really disappointed in that brand, I regret recommending it to friends. ## Features - RGB Mechanical gaming keyboard: Enjoy a Brilliant display of chroma lighting and premium double shot ABD keycap feel with Bloody’s B820 keyboard designed for the minimalist and built sturdy with aluminum grade panels. - Optical Mechanical Blue Switches: Optical switches actuate 30x Faster then traditional mechanical switches.

I picked the blue "Machine Gun" switches and I absolutely love the satisfying clicky noises it makes while I type or game. I found that the actuation time is very fast compared to other keyboards I own and have tried. The response times are ridiculous. After testing this keyboard the "Number 1 fastest" claim may actually be true. Light is the fastest thing in the universe after all... The RGB lighting is amusing to look at and I often find myself staring at it. This keyboard is very worth its $100 price point. I do have some minor complaints though. The font is a bit unorthodox, the "wave" effect is a tad bit choppy, the software is a bit difficult to understand, and some macro buttons would be very useful. Overall, This keyboard is exemplary. The super satisfying clicks and super fast response times are things that the big boys such as Razer and Corsair better look out for. Bloody is thirsty for blood. ## Frequently Bought Together - Bloody B820 Optical Mechanical Gaming Keyboard with Individually Backlit RGB LED Keys Wired, 104 Keys Standard, Blue Switch - MX Blue Equivalent for Windows PC and Laptop - Razer DeathAdder Essential Gaming Mouse: 6400 DPI Optical Sensor - 5 Programmable Buttons - Mechanical Switches - Rubber Side Grips - Classic Black - MageGee 75% Mechanical Gaming Keyboard, Red Switch, LED Blue Backlit, 87 Keys Compact TKL Wired Computer Keyboards for Windows Laptop PC Gamer - Black/Grey --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/38185767-bloody-b820-optical-mechanical-gaming-keyboard-with-individually-backlit-rgb](https://www.desertcart.com.kw/products/38185767-bloody-b820-optical-mechanical-gaming-keyboard-with-individually-backlit-rgb) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-21*
