It does not fit exactly on my Ipod touch screen (the prestamped holes for front side camera and ON-button are not covered accurately and on the edges it is 1-2 mm too small). Moreover, it was not that easy to get it on the screen without any bubbles or hairs, but it is ok.
One may wash it with water and it is still sticking on the ipod.
I had a better screen protection on my Ipod Touch 3, but unfortunalety I cannot remember the company, as it was a part of a kit (including charger etc).
So, the product is ok, but there are better ones.
