I was having a very hard time balancing my camera (Rebel SL3). Balancing the phone was a breeze. But when it's done, he does what he says. Stabilizes pretty well. All controls seem to work fine. Undoubtedly the best stabilizer for beginners. I'm disappointed that they don't provide a cable for Canon. Checking the Gudson website, they charge $15 shipping for a $10 cable. It didn't look good, and now the Moza Genius app has become a disaster. Virtually useless except for object tracking. It's amazing that they record slow motion at 30 fps and play back at 15 fps (1/2x) or 7 fps (1/4x). In any case, the Moza master app seems to be doing its job well.
