I found the headband strap and chest to be well built and all extensible straps, not just a little. Banners is lined with a rubbery material that actually captures the head. I have not tried the suction cup so I can not vouch for it yet.
In addition, the small bag is indeed a cute item no real value - but I found a nice way to use it. I'm on my way to a pool to film some people swimming and I want to start gopro in my purse, to protect so I jumped out of the camera in the small bag and pulled the cords around her . thus, the bag has real value now!
