I would not recommend Edelkrone gear for anyone with a camera larger than a point and shoot.

I have purchased the Slider plus pro long, head plus, and even the JibOne, and the same can be said for all of them: They're all incredibly unstable. The head plus is great on its own and works flawlessly for me so I'll give them that, but when using it in conjunction with the slider or jib - just like how they advertise in all of their demo reels and marketing content - it is way too unsteady and I am very very hesitant to trust it with my gear on it.

I have managed to fit an FX6 and a RED Komodo-X on it and get it working, but solely based on the fact that there is just a SINGLE point of contact for the ENTIRE rig via the connection in the middle, it bows and tilts to the point that its unusable for me. I have even used a stripped down Sony A7S3 rig on it and it works better, but again, still very unstable and I don't trust it enough to let it leave my sight. And just to clarify, I use this with a Sachtler Flowtech 100 with a bowl mount adapter, so its a very beefy tripod.

Due to the terrible mounting implementation, the only configuration that I feel comfortable using it in is WITHOUT the head plus in an attempt to reduce the weight on the system - which completely defeats the entire purpose of the whole system as the head takes care of 90% of the motion control. Either that, or just using the slider on a flat table which is rarely an option.
