The small articulated arm provided is a real plus: it does its job well, you could even say very well, since my gear installed on it exceeds the recommended load (+/- 3.5 Kgs) and all the stars without flinching. The trolley is manufactured and is well studied, wheel bearings are correct (well oiled, silent this is important) and only the plastic wheels is a little cheap compared to the rest.
Considering the price it would be a shame to miss out, it's a purchase I thoroughly recommend.
