PULUZ 360 Degree Rotation Mount Holder Wrist Hand Strap Band for Gopro SJCAM Yi
A part of the review has been auto-translated.
the construction and materials are very good. it is comfortable to wear. it does move and spin a little on the hand. the locking mechanism works well and has a strong hold. it can be a little tricky to get on as you are just using 1 hand. my only minor complaint would be the velcro strap. there are 2 plastic clips a straight and a D. the velcro fasten through the d and not the straight. the end has 2 velcro loop parts that fold back on themselves and don't do anything that i can tell. but apart from that small gripe it is a really good product. if the fastening was sorted out it would be a orsum product. i have bought it to take video while climbing to show hand holds i will probably buy a second one no i have seen the first.
this is the second of these I have bought. I like it as it can be used on hand or wrist. it is very comfortable. it will fit a wide verify of hand sizes but probably works best with hand between 80mm and 95mm across the palm. my only complaint would be the swivel mechanism comes of and you need to make sure you use a tether to make sure you don't damage the camera if it comes off. the first one I bought had a small problem with the velcro as can be seen in the comparison photos. it makes no real difference for the use of the camera mount.
