The Dolly is fine, and run very easily. Just a pity that the bins for large tripods is a bit too small. And therefore the tripod can not spread far enough, what the stability affected. The spread is a maximum of 70 centimeters. A bigger Tripod requires more than 1.22 cm. I do not know if there are also larger Dolly.
On basked of Dolly is every penny, value for money. I can recommend this Dolly without restrictions. And therefore forgive 4.5 punte
