Best product ever

It is way better than any other mechanical keyboards on the market, since it has optical sensors the keys can be removed without affecting the main board of the keyboard.

where i can get less tactile keys like silent which type of key is good?

Answers (1)

Tayyab M. 06/03/2025

This keyboard is good at battery life response time and support All key Anti Ghosting. the keyboard is good but this one is NOTA a Silent one. If you want this keyboard then you have to change the switches. its better to look for another keyboard which red , brown or Black switches which have the quieter keys..

Jai 05/03/2025

where i can get less tactile keys like silent?

Answers (2)

Balasubramanian 05/03/2025

You can buy the Red switches which produces less sound on pressing. Very good for gaming purposes where instant reactions are necessary.

MANOVISHNU A. 06/03/2025

While mechanical switches are more readily available and affordable, optical switches are less common and come at a higher price point. Meckeys.com might have a few options available if you're looking for them.

I recently got my hands on the CB Phantom TKL, and honestly, I’m more than satisfied with it. The build feels solid, and the compact TKL layout saves a lot of desk space without compromising on functionality. The real magic, though, is in the RGB — it completely elevates the vibe and makes every...

Good product - Beautiful Look - Well Build - Nice Sound - Nearest to thocky sound

I have purchased the product offline. I have searched for the product in many places for the last 6 months, but have not found it. At last, I found the product in an offline store in Kolkata. I don't like online products, mostly. Day by day, I searched for the products, but I think there was only 1...

Good quality for the price

A Keyboard with premium features at an affordable price point

I got this keyboard around 4 weeks ago and this was my first mechanical keyboard so I have basically no experience with mechanical keyboards. This keyboard was really good at the price point of around 3100 INR. One thing I will say that it lacks features like usb type c cable which is really...

First of all, You can close your eyes and pick this product Blindly*, SERIOUSLY !!!, The level of Build is just........., the connectivity and the latency management is so so so good , i wrote this review after 10 days use , the touch pad is also smooth like butter , and the trigger lock,...First of all, You can close your eyes and pick this product Blindly*, SERIOUSLY !!!, The level of Build is just........., the connectivity and the latency management is so so so good , i wrote this review after 10 days use , the touch pad is also smooth like butter , and the trigger lock, triggers and joystick is just top level premium, and they didn't mention that it has Clicky bumper buttons, which is way better than that mushy type buttons and it last long than that, and the magnetic joystick and triggers are so good quality !!!, and button style is really great work , and the backlit of play button is just incredible, And it also has macro buttons!!! On connectivity, some windows drivers can cause trouble, but the product is top notch, like almost same level latency as wired mode, the developer of this product did a great work !!!, And there's also light bar on front side which indicates connection type, and through ds4 windows the colour of that indicator is also customisable, and you also put that on rainbow mode on wired mode while charging option, and you also can set bettery indicator and below 20% charging red led or any other custom colour led indicators, And To use gyro " Always do Calibration first" , and it has really really nice gyro, actually it's 3 Axis gyro plus 3 axis accelerometer , like it can't be anything better !!!, And it can directly connect to steam on x input mode wirelessly, in which you dont even have to use ds4 windows, On wireless mode , i played Apex legends and see no latency, IT'S UNBELIEVABLE !!!, I played Batman Arkham City , God of War, Spiderman Miles and Morales, Tekken 8 Ultimate, NFS Payback, Apex legends and Microsoft Flight Simulator and also , Transformer The Game (2004 ig) ,and all works insane! On God Of War it connects and plays directly on Direct input mode with vibration wirelessly so no need to use any third party converter, and also on Spiderman, and on Tekken 8 , If you have issue with vibration motor than try to use Ds4windows and set as dualshock controller output But game like batman nfs payback msfs needs x input, so directly playable on steam or via ds4windows on xinput mode And if you don't want to twik any settings as direct input or x input or anything else, just buy and use stratos xenon dongle, And personally i like the PlayStation button layout, since it gives actual a controller and a Game vibe than the XYAB buttons , i didn't thought about that before but on last minute thankfully i noticed that thing, and the transparent looks is just amazing and the design is like it also looks stock black and just perfect colour ! , And The RGB ........., It's just Just Just Just Just Amazing !!!!!, the way the rgb mode is made , is premium level lighting !!! , and when it's turned off on the controller doesn't lack looks, that level of work on design , any developer watching, you did a great job and made great product, And there's also brightness level you can control and colour cycle mode and stock and amazing rgb mode... It's really really good , I'm just waiting when you guys made Dualsense controller exactly this type, I'll be the Buyer of that too !!!
