I have achieved really great results. Only the delivery status is questionable, the Slider comes with a great bag and a bag for the side panels which can be without tools De / Install.
The slider can be broken with a small Allen and maintained.
Those who do not maintain his tools, should not be surprised about jerking when the pollen or sand suspended in the groove as well.
The slider runs very easily, and can be combined with a screw on the side fix or make running harder.
TIP for Liquid runs:
I reach not to the camera to Sliden but summarize the carriage and use your fingers do I control by touching the rail, the running resistance with one hand. With the other hand I can turn the slider on Statiev or just hold simultaneously.
The results are sharp
Unfortunately, there are scratches on the outside that can be felt clearly if, like me use the slider with braking fingers.
Therefore, I consider a replacement by a new, as I suppose getting a used Slider zuhaben.
