When rested on its side, it's about 12 inches high. I placed this around my Blackberry with the open end to the front, and the buzz problem went away. There does not appear to be any interference with the operation of my Blackberry. It LOOKS funny sitting on my desk, but I can live with that. Next step is figure out how short I can cut it without the problem coming back, and then asking someone to bend a small piece of tin to the same dimensions.
