CASTOR K631 PRO - 65% Bluetooth + 2.4Ghz Wireless + Wired RGB Mechanical Keyboard (Red Switch)

I have faced issues in the beginning days but due to the key placement in this keyboard is close to universal standards when compared to other brands, so I sticked on to it, hoping that I would resolve the connectivity issue. However, I didn't find any solution till date. Trying to use this keyboard in 2.4 GHz dongle mode mostly rather than Bluetooth mode. This keyboard is a pro in most of the segments except below points.

1. Multiple key strokes registering issue (This can be seen only in Bluetooth mode, hence the issue pertains to the Bluetooth hardware).
2. Bluetooth disconnection seen very rarely but not often.
3. Replaced all the stock red switches with the other brand red switches and still multiple key stroke registering issue exists.

P.S: Working without any issues in Wired mode and Dongle mode.

Bluetooth connection suddenly stops in between and space bar is being registered without it being pressed , then I have to shift modes to again make it working such big issue . Even I tried mailing and contacting the service and technical support but no reply.

As a enthusiast it is a bit underwhelming you can get a similar keybord with a knob (GMK 67 but it's barebones so I cant complain) for cheaper*. It sounds decent if you get jwicks black r2 and mod it. The last issue I have is it does not have a daughter borad so you can gummy o ring mount it in the case

Bought this through Amazon, this doesn't have any software support to customize the keys but at this price point, it has good connectivity and good battery life and keyboard looks stunning rather than on the screen/website. Did not approach support team yet, but facing issue when a key is pressed it automatically get pressed n. no.of times and we need to change the modes to get it off. But how ever after researching a lot came to know that it is because of pre-lube applied for the keys. It has to be maintained as there is a spring and other parts. As spare switches are not available at the moment on Redragon website, so ordered from other site and will update the review after using them. Wide range of switches are not yet available on Amazon.

Been using it for at least like 3 months. It's so light, easy to work with and the connections are so fast kinda like lightning. The only takeback is that sometimes the bluetooth connection gets cut and a single key is repeatedly displayed on the screen. Requires to switch it on and off.
