Good Cheap head - Caution: 1/4 "-Stativanschluss!

I had this head ordered to replace the plain unusable series head of my Manfrotto tripod travel.
Fluid damping, control lever (determination of axes, lever mounting ...) etc. function properly and surprisingly good for a head in this price range!
Of course, almost everything is made of plastic, but really well made and by no means "cheap" Seeming.
What makes him useless for me:
The head has on the bottom plate (connection to the tripod) only a 1/4 "screw instead of the usual 3/8"! Thus, it is probably for most commercially available tripods (unfortunately ...) unsuitable.
I saw him briefly tested at another stand, must return him unfortunately.
Would he fit, it would be an absolute recommendation in this class!
