Basilisk V4 Pro Issue

I have a case in with support, but this is super frustrating. 
 

purchased the basilisk v4 pro and v2 dock a week ago. Instantly out of the box was fine for 5-10mins. Then the cursor froze. Only way to unfreeze was if I hit the DPI button or turn off and back on. Then play a little more, boom freeze again. Same issue. Same thing. Doesn’t matter if I’m using the dongle or Dock. Same problem. $180 mouse, should work just fine. Especially it being WIRELESS, that should work no problem. 
 

So I called razer support 2 days ago, they made me do a ton of tests. No fix, it’s “defective”. Send it back get it a new one today. No shit, less than 30 mins of the new one and guess what. FROZEN CURSOR. It’s not defective, I can’t be the only one having this issue. Need a hot fix update and get this working. I sent videos in and am waiting for the better support team to help.
 

I have loved my V3, wish I didn’t get rid of it. I have 10 days to figure it out or I’ll be returning this garbage and getting something else. 
 

thanks

    Same issue here. It seems to be an issue with higher polling rates. I’ve had to lower mine to 1k across my profiles and the mouse has been stable. I am also connecting via the mouse dock v2 pro.

    Hopefully we will get a firmware update soon for this but I have not seen any acknowledgement from Razer on the issue yet. There is a reddit thread where someone posted a response from support was to blow compressed air into the sensor….

    I’ve done everything besides throw it through a wall… waiting for the tech team to help. If no update soon I’ll be returning it.

    Hi, I'm experiencing the same issue, and support hasn't been very helpful so far. Personally, I'm still experiencing the issue even at 1,000 Hz.

    Yeah. Polling rate doesn’t matter. Still happens. Only way I havnt had it happen is if you use the mouse Wired. 

      Exactly the same issue here, happened at every polling rate I have tried so far.
