NEEWER AC001 水中ダイビングリグ アクションカメラ用

This product is well made, lite, and the perfect size for a GoPro making it very comfortable to swim with and attach to your BCD when not in use. The coating should prevent the aluminum from salt water corrosion over time.My setup shows it with 3 other items from Amazon:1. Coiled retractable lanyard with a double carribeaner for my BCD to use instead of the leash that came with the cage, which I now use as a backup security leash for my light in the event my modification described below ever fails...5 stars https://www.amazon.com/gp/aw/d/B0C3B5X7DL?psc=1&ref=ppx_pop_mob_b_asin_title2. Cold shoe ball mount and double ball receiver...5 stars https://www.amazon.com/gp/aw/d/B07N2X7JCJ?psc=1&ref=ppx_pop_mob_b_asin_title3. 2000 lumen dive light with ball attachment...5 stars https://www.amazon.com/your-orders/pop?ref=ppx_yo2ov_mob_b_pop&orderId=114-9733009-4925838&lineItemId=rkqotonsmlksuny&shipmentId=GB34KLKRR&packageId=1&asin=B0B4DKVJ3GThere are other reviews that claim cold shoe connections can loosen on this cage (and other cages from other mfgs) causing your attachments to slide out. Those claims are accurate. This seems like less of an issue with the cage and more of an issue with the item that you are connecting to it, which in this case is the cold shoe ball attachment in my photo. Fortunately, there is a super easy fix...a 12-inch long rubber gear tie. When you tighten the wheel down on the cold shoe it creates a gap between the top of the wheel on the attachment and the flange on the attachment is a perfect fit for the gear tie to sit in. Wrap the tie around the threaded post in that gap like I have shown and twist it tight once, then wrap the tag ends under the cage frame and back over the top. There is now no way the wheel can back up to become loose because it has no room for it to unscrew.The reason for the 4 stars instead of 5 is what another review called out. The GoPro mount that is provided with the cage can easily come loose and whatever camera you have can fall away into the deep. The issue is the slick metal GoPro connector gets tightened against the slick metal frame and with not too much of a nudge on the camera, smooth metal against smooth metal just loosens quickly. The mfg tried to install a small horeshoe type rubber pad to prevent this but it is simply way too thin to create a firm lock. The solution that should have come with the cage is rubber washer/grommet to sit between the frame and the camera mount. The one in the picture is the best I could find in the home hardware supply but it is too thick and does not have a large enough diameter as shown in my photo. Off to the hardware store for this item. The mfg could have easily addressed this and saved me the trip.
