I really looked forward to using this gimbal since it's purported to have great features: small, light, foldable to a compact size, able to accommodate phones up to 88mm in width, plus a copious assortment of fantastic features: pan/tilt mode, sport mode, inception, etc.However, before I even turned it on, I ran into the first showstopper: the clamp will not accommodate my phone. In fact, it looks like it'll have trouble with any phone that's thicker than about 5 mm.The clamp has square notches on either side into which the sides of phone should fit (see photos). But those notches are less than 5 mm. Sure, if I tilt it, one edge of my Nexus 6 will fit in one side, but then, because the back of my phone is not flat, there's no way the other edge will fit into the opposite notch.I did manange to jury-rig it so that my phone is held by the clamp with neither edge in its respective notch. But then, because of the spring pressure holding the clamp closed, the phone is in a very precarious position: if either edge slips out of the clamp, the spring pressure will slam the clamp closed and pop the phone out with force.That happened to me twice, but fortunately I was sitting down and I could catch the phone in my lap - it's ejected way too fast to catch it by hand. If I'd been outside using the gimbal like it's supposed to be used, and the phone was was popped onto pavement, it's like *throwing* it onto the pavement ... bye bye phone.OK, suppose the clamp worked. But then the gimbal has another big problem: it inconsistently responds to your button presses. To change modes, you have to press a certain sequence of buttons a certain number of times. But the buttons do not positively "click", and so changing modes is hit or miss.This problem is compounded by the fact that the gimbal app DOES NOT DISPLAY THE CURRENT MODE. That's inexcusable -- not only is it hard to tell if you've pressed the buttons, but the app doesn't tell you if you've changed modes. So you're forced to try moving the gimbal and guessing which mode you're in :-(Can you imagine telling your talent to please standby, I'm trying to figure out what the &^*! mode my gimbal is in?Because of these faults, I'm afraid that the Mini-S will either cause me to break my phone, and/or be a total frustration when trying to use it. Not happy because I spent many hours trying to make it work :-((Thank you, amazon, for your accommodating return policy.
