The robustness cheap

+ Exceedingly strong, designed with robust materials (which make it also quite heavy - which is a pretty good news for a camera foot - and offered bag makes the job even if it is not amazing either, it necessary to provide another transportation solution if you are mobile)
+ Very tall, its height makes it incredibly versatile. This size for such a price is THE foot.
+ Small rubber feet to prevent damage to your floor which also makes the perfect grip on smooth ground up, you can remove them if you are filming / photographing on soft ground (perfect for indoor / outdoor use)
+ Clamps / successive loosening not altering (at least for now) nothing in the rigidity of the assembly
+ Solid handles, handy head ...

- ... Even if I work primarily in fixed shots therefore the mobility of the head does not bother me really problem. However, you may need to tame the beast to make your ultra smooth tracking shot.
- The "tabs" to block the feet are a little fragile and cheaps however; they are sometimes capricious. Once in place, however, nothing moves.

Recommended. For a price like this is really amazing.
