The carriage has game that does not fall at the beginning perhaps so much, but after some time (1-2 months) it wobbles more and more. . Thus, selected motifs are not reliable, the camera tilts forward / back and then it was all the sound service, the plastic sleeves in the sled "used up" - send in for repair would cost just under 40 because of the size of the package (bulky goods). I think it is for a construction defect.
The feet are not gummed but of hard smooth plastic. Stable yes, but slip on smooth floor. Thus, the use is only possible on a tripod, or even on and so "rough" ground like grass, soil, brick which restricts the use of an enormous.
The rail has on the sides no "stopper" for each rotation you have to screw the feet (each 2 fipsige screws are tightened using an Allen key fipsigen). I think that's not very well resolved.
The only positive thing I can abgewinnen the product: It is included a padded bag.
