Black Widow V4 restarting non stop

First my brand new BlackWidow V4 couldn’t handle 3 profiles and me switching them manually. It kept resetting.

Then couple days ago it just turned off for 1-2 minutes for no reason couple times. Reconnecting usb did not help only waiting. Then it went black completely. I did hard reset by holding Spacebar+CapsLock+Esc before plugging in. It worked for a while. Today after turning on PC it kept resetting non stop. 

I reinstalled synapse, drivers, checked on other PC, reinstalled newest firmware. Keyboard works if there is no synapse running and keeps restarting when synapse is on. 

So my question is: Which mechanical keyboard with macro keys and fully programmable buttons should I get once I get a refund for this junk.

This Keyboard is frustrating indeed. Light settings keep resetting, synapse has to be launched to restore backlight, cause it is still restoring to “wave” despide the fact I deleted all the dynamic lighting profiles, left only static. Keyboard keep disconnecting while wireless. Has Naga V2 Pro, It was working acceptable, until BlackWidow V4 was bought and connected. Power profiles are unpredictable, waking up sometimes work, sometimes i have to click it for minute. Mouse started disconnecting, even tho they are on diferent dongles (That “hyperspeed” “multidevice” pairing causes only more problems… When OS is going to sleep i had to connect other keyboard to wake it up - so it is not PC/OS USB problemm...) . I was relatively content with Naga V2 Pro, now I am disappointed as a whole. Cant return it, but probably never gonna go back to razer when next purchase will be considered.

Exactly my setup: BlackWidow V4 and Naga V2 pro. I had keyboard first but together problems multiply. I returned BlackWidow V4 for full refund - they didn’t managed to make it work in time. Now I have Corsair K100 RGB with my Naga V2 Pro and it works more or less reliably. Had to make another default profile to profile switch when it get’s stuck sometimes though.
