NEEWER 3-Wheels Wireless Video Camera Dolly, 3-Speed Motorized Electric Track Rail Slider Dolly Car with Remote Control, Compatible with DSLR Camera, Camcorder, Gopro, and Smartphone

very high quality dolly that lets me record without holding the camera at all times

Great for improving your video values with smooth tracking shots . Will take anything from a GoPro to a DSLR. Be prepared to Overlay audio on the tracking shots as the camera will pick up the motor noise. The remote control is a nice touch & makes setting up Shots a lot easier . I bought this as a gift for someone but I’m gonna get one for myself as it’s great fun to use.

Does the job to a degree but the on-off switch seems to be faulty so I’ll be returning it. Very hard to get it to do the perfect circle. Not the best but for what it costs it does a decent enough job I suppose.

Saw one used on YouTube thought mmm nice idea.Its worth every penny .Adds so many new ideas to shoot video on osmo pocket. Buy try I don't think you will be dissapointed

So far it has worked well for me, though I've not yet used it extensively.

It's very easy to use and does the job I wanted it for. I think it's really more suitable for smartphone and sports cameras, rather than a DSLR. But, to be fair, I need to do more testing with my DSLR. Update: 24 June 2010 OK, I've now had time to run some tests with my Nikon D3200 on this item. Very disappointing. Unstable is the best word I can find to describe the performance. I tried to run the dolly with the same dslr on my Neewer camera track... very inconsistent at all speeds. The dolly (and hence the camera) wobbled excessively. Considering the dolly is advertised as being able to carry a dslr on a Neewer track, I found the advertising far outweighs the actuality. As I mentioned in my first review (see above) the dolly is best suited for camera phones and GoPro style sports cameras. I had hoped to be able to give a positive review, but alas I can not. This is a real shame because I have usually been very impressed with Neewer equipment.

Worked for a couple of minutes then stopped. Have to return it for a refund. Waste of time and money.

Looks ok, and has the load capacity I want. However, be careful if you intend to by rails for this to run on. The 40cm track that is suggested in the 'buy these' options is too narrow for the dolly. The track rails need to be 80mm apart for it to work; of course, I bought the 40cm track suggested. At least I can use it by itself.
