Super tripod, the quality looks really good for the price (so small compared to others) not forgetting the 10 year warranty. It is also the smallest folded tripod height, I looked at Vanguard, Manfrotto and Benro, nothing so compact, everything is often a few centimeters higher, and especially more expensive. The opening at ground level is a superb idea quite rare on tripods, much remains to be aware of the maximum height and therefore know well its needs. For the kneecap "RB5.1" this is a very good surprise, it exudes quality, no play and movements are clean, especially panning, it's a great surprise, it is ultra smooth and allows shooting smoothly (see youtube). The only flaw is the lack of quick release plate on the ball, easily rectifiable default by purchasing an adapter (about 14 on Amazon).
For the rest it may be helpful to note that on the high central column, there is an adapter for the pitch of the ball, it will transpose adapter on the small column that is provided, it may -being silly but trying tripod I thought there was a problem, so that the adapter is for both columns.
In short, I recommend for photographers who need maximum compactness, affecting the macro or working near the ground anyway, and those who play a little video outlet.
