This is a pretty neat little device! I gave it to my nephew and he stuck it to his phone and has been playing with it non-stop ever since! It is easy to attach, just peel the paper off of the back, place it onto a phone or table (you could use it on many things, really) and press down firmly (i heald it down firmly for a few seconds) and it is good to go. It has a strong bond and holds on to the device well. I imagine if it had to be taken off, any resadue could be removed with goo gone.
