On my iPhone 17 Pro, it's really stable on the MagSafe and doesn't accidentally slip when I hold the cell phone a bit more slanted or use it with one hand. I mainly use it for selfies and video calls in the evening when the room light isn't enough, and the difference is huge - the face is evenly illuminated, without harsh shadows or bright spots. The magnetic force is strong, the light holds well even with my normal case. Thanks to the small extendable arm, I can position it in such a way that neither the camera nor the image section are covered - even adjusting/turning is no problem. I also find the integrated mirror handy, so you can quickly check whether everything is in place before you press record. The workmanship looks high-quality, nothing wobbles, the joints can be adjusted cleanly and then remain in the selected position. The light itself is pleasantly soft, the brightness and color temperature can be adjusted continuously via the wheel - from warm and cozy to more neutral/bright for calls. In everyday life, the item is packed super quickly, fits easily in your pocket and is therefore almost always with you.
