The build quality is better than expected, everything very solidly built. I even installed a Panasonic AG-AC90 E (That's a SemiPro camcorder, about 2.7 kg!), And therefore filmed (pretty adventurous, but it works!). The wheel does not turn as easily as it is known from in-line skates, but I could not feel any disadvantages in this regard. For the filmmakers of only every now and then the Mini Dolly needs, absolute buy recommendation!
