Mavmount all the way. Can't beat the quality but it's a pretty penny. For a mount the pricing is more expensive than most of the mounts out there. At the end of the day I like quality items and although I vow that I wasn't going to spend so much on a mount, I finally did because of these main reasons.
- Mavmount mounts the tablet in a balance fashion. In other words, with the mounted tablet/phone, the mount allows the controller to sit up right. It's a minor thing but when you're holding it or have to set it down, it sits right (balanced). Hard to explain but there was a video about it somewhere, I'll see if I can dig it up.
- Secondly, it allows multiple mount points. For instance on a Mavic controller, I can have "dual" screen where I can see the controller screen as well as the tablet or I can mount it so it completely covers it. I know it shows the same information so why do I need it to be dual screen? But little details of the options.
- Ballhead. I know some mounts have ball head as well but I like how they made it both a ball head and it can turn in different direction with one little knob.
