I have tried a few neck holders and always been disappointed at some level, but this is by far the best I have seen and I may finally have found one that is genuinely usable in a range of situations.Breaking it down, the neck band is made of a comfortable and malleable rubber that is easy to shape and feels well made with a high-quality finish. It is closed by inserting the right-side pin in the socket, but requires the nearby release slider to remove, so you are protected against accidental drops, while remaining practical.This then attaches to the GoPro-style mount that can be used with any number of action cameras, such as the DJI Action cameras with a suitable adapter, but the part I liked best is the metal MagSafe adapter that can be used with my iPhone 17 Pro Max and attaches like a limpet to a rock with angled flexibility. There is another option to pull out two securing leavers at the side, but I found no advantage here in terms of stability and it was maybe worse on the iPhone, so I assume this would be more of use to Android users.Finally, there is a securing strap that goes around the chest and tethers the mount, so it doesn’t bounce around wildly when in movement. This is fairly typical; however, it has been done properly here with higher-than-average quality and good Velcro fixings. If you want a high-quality neck holder that covers action cameras and phones, I recommend this one.
