Despite mixed and some rather harsh reviews on Youtube I recently purchased a second hand OM 4 and I have to say that I'm very positively surprised. I'm using it with an Iphone 11 and I see non of the issues being pointed out in several Youtube reviews. I suspect that the reason why it works so well is because I'm using an rather powerfull Iphone.

• The gimbal is super stabel and having calibrated it only once it's just super level every time I use it
• I do not have to balance the phone ever
• The magnet system works super and just clicks on
• The gimbal gives the impression to be very robust even for my outdoor usage
• All functions work and are very intuitive to use (timelaps with path is really cool and tracking really helps me in my active outdoor movie making)
  

Only thing I would like more is:

• That the DJI Mimo app would open when I turn on the OM 4 just like the DJI Fly app does
• Remote controller to remotely start, stop, zoom, track and move gimbal
  

ohhh yes, and then I'm really anoyed that DJI will not allow to move over a second hand product to my account........   

Hello there Turfolk. Good day and thank you for sharing your valued insights with regards to this matter. I will forward these information to the designated DJI department for further attention. Thank you.
