I have a RAM mount as well, and it works as you say. I guess I wasn't clear enough. The material used for the suction cup on MY 740 mount is exceptionally sticky. It's like those mats you put on your dashboard and just lay the cell phone on and it never moves. That seems to be a good feature for mounting and being assured it's not coming off any time soon. But having to take it off each time I use it, it sticks a bit too tight. I took a picture of it. That pen is just pressed onto the suction cup. No glue, no tape, no tricks. I didn't time it, but even with moving it around and the pen swinging back and forth, it held for around a minute, perhaps more.
