A Gumby-style bendable cable mated to an iPhone grip, and a clip that can affix nearly anywhere, make this stand super useful!
AboveTEK's bendable iPhone holder is amazingly handy. Now technical diagrams or simply directions can be available, right in from of my face. I can clip it almost anywhere I am working and have already found great assistance while working on a motorcycle, and cooking in the kitchen.
It is very stable, but I'd warn against suspending the phone over water. Keeping a stylus handy will also save you (me) trying to use your nose to flip a page while cooking.
