This product is a sturdy, 3 wheeled dolly that is workable with most tripods. I say most as some professional tripods can weigh a lot so this wouldn't be appropriate as a dolly system could be. The build, whilst slightly ruggedly put together, does do the job well. However, it is the 'job' that I have most gripes with.
As the wheels oscillate independently and have no way of locking on one parallel plane with the other wheels to create a controlled lateral movement, this dolly is really only appropriate for light stand manoeuvrability and some dextrous camera movement providing the floor surface permits. The wheels and frame do cause judder when there is excessive movement but as there is a locking mechanism for the wheels, it's most successful as simply a way of moving lights etc. between shots. Slow movement can be controlled but this is only minimal. The only way to create a solid track shot is to manually hold the wheels so perhaps a wheelchair would be more efficient if that's why you are buying this.
The package is good; a carry bag accompanies the foldable dolly and it fits nicely. The overall size folded is very compact and its weight is slight. The unfolded dolly is considerable so you have to think about room for it if you have more than one.
To surmise, it's a competent product. I think it's a very cheap and relatively effective purchase, too. It might not have a great look but it does do a good job for what it is. Recommended buy.
