When I got the V2 faucet in the mail I was happy to use it. I bought the faucet for my 5d mk.iv so I updated the firmware when i got him increase the payload to hold 5D after i installed everything i powered it up but the motors were dead seem to have no clear solution for this I am very disappointed with this product now because it remains useless now I have contacted Zhiyun support and am currently waiting for their response But for now I would not recommend this product until it there is a clear solution to solve this problem.
