Wow, am I happy that I came across this little gem of an item!
I can now use it to hold my iPhone perfectly, and it will be great for using it when watching movies, TV shows, or live TV. It can bend in many directions, but stays perfectly still and does not move around at all. I have not tried it in a car or a moving vehicle, so cannot comment on that, but I am delighted that such a fantastic little product was available here on Play.
If you think it will be of use to you, you will not be disappointed.
