Product looks a little different than picture, longer than it is shown. It does not have two holes on the back to hold it in place and protude out further than other bluetooth. It worked fine on the desktop USB slot, but it does not do too well on laptop. I had to push it in just right(not all the way in and I had to feel for friction), if I touch it afterward, it lost connection with my bluetooth mouse.
