I bought the MOZA Mini-S stabilizer a few days ago, I'm glad this stabilizer is so small and foldable, compare with the Smooth 4 of my friend Zhiyun, which I can easily put in my small rear camera bag, see photo. Another hurdle for me is that I can attach a wide lens to my iPhone x max (zoom the wide lens to 18mm) and still hold the MOZA Mini-S gimbal very well, the Smooth 4 doesn't even balance with the wide lens attached, the is very important to me, because in most cases you really need a wide-angle lens to shoot videos. Another benefit of this gimbal is that no arm adjustment screws are required to balance the cellphone. It is enough to plug in the phone, which makes the installation of the phone very easy. Works very well with 3-axis balance, no difference from Zhiyun Smooth 4.
