I purchased Loop Quiet and Loop Engage plugs. The Engage worked immediately once I got my right size, but not at all for the Quiet. I think it has to do with the fact it was a lot easier to twist in the Engage because of the hard plastic used for the body of the plug, the quiet is a soft rubber that does nothing to help with twisting it in. I used all the sizes and tried various methods (including the one in the video) and they just won't stay in or go in.

I'm pretty disappointed, as I especially wanted Loop Quiet because I have been having awful sleep as of late. I'll keep trying but if anyone has any suggestions or advice that'd be great.
