Excerpt: I am a professional videographer and purchased this little addition about 2-3yrs ago. I cannot imagine how I lived without it. It is great. Like many other said, the only down side is the stopper is way too low. It get's stuck on anything that is not high enough off the ground. If they fix that issue, it will get a 5 star from me. I have not done so, but I plan on trying some weight and hope that helps.
Pros: Easy To Use, Fits Well, Improves Tripod Function, Solid/Sturdy
Excerpt: Secure tripod legs perfectly, adjustable locks are reliable and this dolly can go through any door easily. Center lock works great if adjusted correctly. Dolly does not roll well on carpet but I knew before getting it. To fix the break problem, I opened the wheels and add 2 washers ($3 total). I also added 12 skate dolly wheels and got dolly track ($100 total online). It makes perfect smooth cinematic motion, like Kessler dollies (from $700).
Pros: Easy To Use, Highly Compatible, Improves Performance, Lightweight, Professional Quality
Excerpt: Great and easy to use. Like many have said, the locks hang on carpet. It does not look like a grinder will solve the problem. It works for me, but you must use care when rolling on any carpet into which the wheels will sink into.
Pros: Easy To Use, Highly Compatible, Professional Quality
Excerpt: Construction is great, and if used in a completele flat and polished floor, results are great. It doesn't fold that much, and as many said the brakes are too close to the floor. If you roll it on any surface where it gets vibration (obvious, recording would be completely useful) but watch for the nuts, and bolts as they fall down.
Excerpt: Having just set up a new studio, this inexpensive dolly was just what we needed to give us smooth moving shots in the studio. The width adjustment allowed us to fit a variety of tripods, and the ability to raise the dolly off the wheels for a lockdown shot is helpful; although, I wish the pegs we a little higher when rolling on carpet.
Pros: Compact Design, Easy To Use, Improves Performance
Excerpt: I agree with one of the reviewers that the brakes are too close to the ground so it will even get caught on very short carpet. That might not be big deal for a lot of people, but if you are using it on location (office location), not all clients will have cement or hardwood floors. But all in all it's portable and it's one of the better cheaper alternatives to professional movie dollies.
