Run really small! Worst packing there is no box. 5 and read that they run a little big so I got the 7-8 size and they fit perfectly! Does Apple really need that much profit? Seriously, this is price gouging. After installation and using in the field, I have found the light produces a lot of RF interference. Don?t know how to do backflips or sustain a body slam? No problem! Had no choice but to buy it coz theres no other storage product like this on Amazon. Truly, I was quite impressed with the AT-VM95E cartridge which sounds quite good through my system. I loved the fact that it was thin, lightweight, and did its job -- while it lasted, that is. The panel seemed to work right out of the box after downloading and installing the Logitech driver.
