Review: • Performance- Performance will be the same irrespective of what keyboard you have, but the thing matters is the responsiveness, sound, feedback etc. • Keys and personal experience- keys are good at this price range and are pretty responsive. You will get 1000hz of polling rate. This is my first mechanical keyboard, before I was using a membrane keyboard. It is much satisfying to type than membrane keyboard. Sound is as expected. Initially, while typing there is a high chance of getting some random keys being triggered as the keys are quite raised but you will get adjusted after somedays. So I would recommend to use a keyboard wrist rest for mechanical keyboards. But after all it is upto you. • Lighting-Lighting is ok, but is it not TRUE RGB, you can't assign specific colour to the keys, there is a specific light for every row, but there are 20 light modes. Brightness is noticeably low in daylight but at night it's good. • Sound-If you are confused about the sound then don't worry, it doesn't make much sound if you type lightly. But if you type by pressing hardly then the red keys also make noise, but blue keys create more sound than red keys, if you want sound and best typing experience, then go for blue keys. But if you want less sound then opt for red keys. • But which keys for gaming? Blue switches have good tactile feedback than red, which gives more satisfaction. So bcz of the tactile feedback and the sound, blue switches feels more satisfying. Red switches are smooth, which requires less effort to press and is good for fast movements like esports. Hence red switches are more responsive than blue switches. Now it is upto you.. • Weight- It's heavier than membrane keyboards because you get a metal body which is absolutely fantastic. I have not weighted it but it feels much heavy. • Some TIPS- If you need to change the keys then don't pull the keys with the keypuller, as the keys are soldered on the pcb(i had checked it), it could damage your keyboard. so if your keys stopped working and you need to change the keys then you need to open the keyboard, desolder the keys and then you can change the keys. though it is mentioned that is it hot swappable but it is actually not. Maybe my unit was faulty but it maynot happen with your unit. Like one of my friend has blue switch variant and his keys arent soldered, it can be pulled. So make sure to check that out before changing. • Disadvantages- One thing I would like to mention that I am not satisfied with the grip, the right side of the keyboard slips sometimes, and the grip also becomes less when the keyboard is raised. But this may not happens with your ones. Another major disadvantage is that when you turn on the windows windows lock, there is no indicator. A very low light glows at the numlock, caps and scroll lock section, but its almost impossible to spot that unless you look very minutely. And also there is no indicator of the all keyboard lock. And there is no FN lock key. I think instead of whole keyboard lock, they should give FN lock key. It is uncomfortable using the media keys like volume up volume down. Everytime you have to press and hold the FN key. • My suggestions- Definitely this keyboard is good at its price range and you cannot expect everything to be included. If you get this keyboard within 1800, then definitely buy it. But if it is of 2k or above then I would recommend that to slightly increase the budget and buy keyboards of 2.5k range and the redgear shadow blade. If you can afford that then definitely buy the redgear instead of this one. But if you are tight on your budget then buy this one. Edit: 1.5 years passed still working fine.. no issues..
Review: People with 5 stars have probably not used this keyboard much long. Don't believe youtubers also. I have used 2 of this same keyboard one I bought in 2022 (same keyboard with non swappable switches) and stopped working after warranty was out. This is second one bought in 2023 Dec and already had problems so once I got it repaired under warranty. But now again causing problems and is out of warranty. Changing switches doesn't help and keyboard will stop functioning before switches can be even changed so that is a complete useless gimmick feature. First time I thought its is a problem with my unit, but I have used 2 of these now and both not even lasting 2 years. Youtubers hyping this are not actually using the keyboard and reviewing only based on first impressions. Rather spend some more and get a better keyboard that lasts long or spend lesser and get cheap or non mechanical. Complete waste of money. Typing experience is also not that great and single click will give you multiple inputs many times (this is when the keyboard is fine)

As I sit down to write this review, my fingers dance across the keys of my trusty mechanical keyboard, each press accompanied by a satisfying click that resonates through the room. Three months into my journey with this keyboard, it's time to share my thoughts on what has become an integral part of my typing experience. Red Key Caps: A Symphony of Sound One of the standout features of this mechanical keyboard is its red key caps. Not only do they add a splash of color to the design, but they also produce a sound that I find particularly delightful. Each keystroke emits a crisp, satisfying click, providing auditory feedback that enhances the typing experience. Whether I'm typing up a document or engaging in an intense gaming session, the sound of the keys adds an extra layer of immersion that I truly appreciate. Comfortable Typing Experience Beyond the auditory pleasure of the red key caps, typing on this keyboard feels incredibly smooth and comfortable. The keys are responsive without being overly sensitive, allowing for precise input with minimal effort. The tactile feedback provided by the mechanical switches makes each keystroke feel deliberate and satisfying, resulting in a typing experience that is both efficient and enjoyable. Sturdy Design In addition to its excellent performance, this mechanical keyboard boasts a sturdy design that exudes durability and reliability. Constructed from high-quality materials, it feels solid and well-built, capable of withstanding the rigors of daily use without showing any signs of wear or tear. Whether I'm typing at my desk or transporting the keyboard to a different location, I have confidence in its ability to withstand whatever challenges come its way. Cool Lighting Effects For those who enjoy a bit of flair in their setup, this mechanical keyboard offers customizable lighting effects that add a touch of personality to any workspace. With a variety of preset patterns and the ability to create custom lighting profiles, users can tailor the aesthetics of their keyboard to suit their individual preferences. Whether you prefer a subtle glow or a pulsating rainbow display, the lighting options are sure to impress. Final Thoughts Overall, my experience with this mechanical keyboard has been overwhelmingly positive. From the satisfying sound of the red key caps to the comfortable typing experience and sturdy design, it ticks all the boxes for what I look for in a keyboard. Whether you're a writer, gamer, or casual user, this keyboard offers a premium typing experience that is sure to enhance your productivity and enjoyment. And if you're someone who appreciates a bit of visual flair, the customizable lighting effects are the cherry on top of an already exceptional package.
