DREAMGRIP WTD-300S Home/Office/Studio Dolly for Shooting with Moving Camera Smooth and Seamlessly on Any Tripod; Heavy Duty; Compatible with DSLR, VCR, All DREAMGRIP Tripods and Evolution Series Kits

I was a little concerned that the price would indicate something weak but Im happy with how effortless it is to move my studio on a tripod around now.Its based on a Manfrotto 075B tripod I bought in the 1990s for a Horseman LX 5x4 studio camera (heavy).I was concerned about lifting this heavy tripod to relocate it as it has magic arms attached to the tripod to hold a Ninja V as well as the glide cam teleprompter on top. Its now just a matter of gently pushing into position.On a smooth surface it could act as a dolly in the traditional sense though I would have thought you would need to build rails for it to run along if you wanted control, I might give it a go for the occasional tracking or moving shot but in reality its for locating the heavy equipment quickly and safely.Each tripod leg tip is approx 29" from each other when the dolly is fully extended. The weight of the tripod is concentrated into the wheels so it feels very stable. The large rubber feet of my tripod fit into the tightening mechanism fine. Comes with a very strong bag which I will probably never use as this thing is going to stay assembled and ready to go.

Using for Elinchrom light system, rolls nicely, would order again.
