I've been on 8g and the size for a while up to 6 g was so big that I was worried that I would explode. I cut off about an inch and a half of tape, then cut this strip in half lengthwise and wrapped it around my corks. they came in with no problem and the tape stayed in place; it didn't move or wobble when I put it in my ear. I've since added another stripe to my corks over the first and it all came together perfectly. I definitely recommend it, especially for the price. You get a lot of tape on a roll (at least when it comes to how much you need for end caps) so you don't have to spend money and time trying to find a half size to use once.
