Great RGB Keyboard
great keyboard. keys are not clicky at all, very light, good for office work with a little light that you can change to either breathe or steady, and has 4 light levels of brightness. good compatibility durability USB plug in no installation

Would be great if it held a charge
I’ve only had it for a couple of days but so far I’m liking this keyboard. The only issue that I’m currently having is that it won’t hold a charge. I left it plugged in overnight and when I disconnected the power cord, nothing worked. I can only use it when it’s plugged into a power source which technically takes away from it truly being “wireless”. I’ve contacted the company for assistance so my rating may change depending on the results. My only other complaint is that the keys aren’t as bright as I might like but I love all the color varieties.The typing aspect of this keyboard is amazing! The keys are super smooth and quiet! Overall, I really like it so hopefully they can help me figure out why it won’t charge so I can keep it.UPDATE: I received an email back from the company telling me that I needed to contact Amazon’s Customer Service department to either return or replace the product! No troubleshooting questions, just “call Amazon”. I did call Amazon and they, however, were very helpful! I received a replacement faster than when I ordered the original! The company contacted me again (after I gave 3 stars), telling me that they would like to address any issues or concerns and to reply back so they can work to resolve my issues. After replying that Amazon has already resolved my issues, they apologized for the inconvenience and that I should contact them if I have any issues with the new keyboard. To be honest, I’m thankful that there have been no issues so far because I’m not confident that they wouldn’t just send me back to Amazon again. So far, this keyboard is working the way it should and I really like it! I’m going to change my rating from 3 stars to 4. Now that I have a properly working product, I really like it but I’m only giving it 4 stars because the Company’s “Customer Service” is lacking in the “service” department.

Bought 2 of these keyboards. Both stopped working 5-6 weeks after purchase.
When I purchased the first Redragon K509 keyboard, I also purchased a Redragon S107 keyboard and mouse combo at the same time. The keyboard in that S107 combo looks identical to this K509 keyboard. It even has the exact same instructions, looks identical, and behaves exactly the same. This K509 keyboard appeared to be a good value. I felt the quality was good for the price. The LED’s were not fixed colors (which is good), and the LED’s could be set in many colors, in “breathing mode” and constant brightness. However, when set to constant brightness, the lights dim a significant amount. I could live with that.I would give this K509 model a fairly high rating, but after 6 weeks, the first keyboard stopped working. Windows would no longer recognize the device. I tried plugging it into different USB ports, but that made no difference. I tried using the keyboard on 2 other PC’s, and they had the same trouble recognizing the device. I figured I just had bad luck, and ordered a second, exact same keyboard. After 5 weeks, this second keyboard started having the exact same trouble. Windows would no longer recognize the device. It couldn’t even tell it was a keyboard. Again, I tried this keyboard different USB ports and on two other PC’s. It would not work no matter which port or PC I plugged it into. Other devices, including other keyboards, work on each of the USB ports I tried on the 3 different PC’s. I also have a Redragon S107 Keyboard that is part of the Redragon S107 Keyboard/Mouse combo. That keyboard still works great, and looks and behaves identical to the K509, except for the label underneath the keyboard. The S107 keyboard (not this KB) works just fine on all 3 PC’s, and I still use it without trouble, to this day. I have contacted the manufacturer and attempted to get support for this product, multiple times, and they said that it was a problem with the USB port, and to plug into another port. I had tried this, as well as trying the keyboard on multiple USB ports on two other PC’s. The manufacturer would not admit that the problem was with the keyboard. I was given instructions how to remove the unrecognized device in the Windows “Device Manager”, and let windows recognize the device again. This had no effect. After the problems began, each time I plug in the keyboard, it would light up for a few seconds, the PC would make the typical “USB device attached” sound, then the light would turn off. Two or three seconds later, it would light up, PC makes the sound again, and lights turn off. It would repeat this for various number of times, before the keyboard would eventually have the lights stay ON, and look as if it was working, but none of the keys would respond. When I check Windows 10 “Device Manager”, I would see the keyboard listed as “Unknown USB Device (Device Descriptor Request Failed)” The Device Status read as, “Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor failed.” I like this keyboard. I would purchase another, but I worry that there may be a design or manufacturing flaw, causing an increased chance of the device failing to be recognized by the PC. I have only tried two of these keyboard, so I cannot be sure. But 0 out of 2 is not a record that would inspire the confidence for me to recommend this keyboard to anyone.I get this exact same behavior and error on all 3 PC’s… an HP desktop, a Dell/Alienware desktop, and a Microsoft Surface Pro 4 Tablet PC. My Redragon S107 Keyboard and mouse combo continues to work just fine. I have an older USB keyboard being used instead of the two Redragon K509 keyboards. Neither K509 keyboard was damaged, dropped, or misused in any way. They get plugged in, and remain in a fixed position from that point forward. No food or drink is consumed near them, because they are located around other sensitive equipment.I should have attempted a product return on Amazon, but it was already outside the window of time I could return or exchange the product. That is on me. However, the manufacturer still would not admit that the keyboard was defective in any way, in spite of the obvious evidence to the contrary.

muy buena calidad y se ve muy bien calidad precio

The Redragon Dyaus K509 is an excellent choice for gamers seeking the perfect balance between affordability and performance. Despite being a membrane keyboard, it offers a **semi-mechanical feel**, providing tactile feedback and a satisfying keystroke that closely mimics mechanical switches. This makes it ideal for both gaming and typing, delivering a responsive and comfortable experience.One of its standout features is the **vibrant RGB lighting**, with numerous color modes and dynamic effects that add flair to any setup. The low-profile, ergonomic keys ensure minimal fatigue during extended sessions, while the build quality is impressive for the price. If you’re looking for a budget-friendly keyboard with a **mechanical-like typing experience**, customizable RGB, and reliable performance, the K509 is one of the best options available.

There are 7 solid colors to choose from for the back lighting.(plus 3 red / green / blue offset patterns)It has a good layout, easy to read letters without any fancy “Gamer” style to the font.It looks clean and simple.I do occasional typing and occasional gaming.The USB cord has a decent long length.At first I couldn’t get it to stop “breathing” of the light level up and down and that was annoying. I looked for software for this keyboard on the manufacturers website, they have tons of keyboards similar to this model that have software, but there is no software for this model. How do I get it to stop breathing or flashing crazy like a Christmas tree?! Ahh! Then I figured out how to get it at just One color – always on without breathing or flashing. After power on of the computer, hit the right Fn key and the Page Up (LM3 – “light mode three I assume”), this first step will lock it to not breathing or flashing, then hit right Fn key and Home (LM2) until you get the desired color you want, tada! You can then use Fn key and arrow up or down to set how bright.It is sort of annoying having to do this every time I power on the computer, but I actually prefer to not have to run extra software on the computer just for the backlight of the keyboard, so for me its fine.
