I am very happy with this ViewFlex phone setup. The quality is excellent in every respect, with a very strong and durable aluminum alloy construction that should hold up well in almost any environment. The handles have a nice rubberized finish that's comfortable and sturdy. The phone holder is firmly attached and expands enough to hold any size phone. It also features large, oversized top and bottom grips that securely hold even large phones in bulky cases (like my Samsung Galaxy S21 Ultra). Mounting options are plentiful. There are four cold shoe mounts (one at each end of the top and bottom rails); two 3/8" holes (one each on the right side of the top and bottom rails); two M4 holes on both top rails; seven 1/4" holes total - two on the top rail, three on the bottom rail (one in the center for the tripod or handle) and one in the center of each handle that allows you to use the portrait orientation with a tripod or handle. It only includes the mobile accessories or accessories you need to record videos on your phone. The Bluetooth shutter module is very basic but works flawlessly and fits nicely in the slot on the right side handle for easy two-handed operation on the setup. There are no complaints about this item and I would definitely recommend it to anyone interested in DIY phone videos looking for a really well made and functional cage.
