I tried them and found the rough edges cut my tubes. Had to abandon them. A good example of going one step of lightening too far. Just my experience. Otherwise I really liked them. Tremendously convenient for getting at one spoke.
Just looked at some old "data" of mine when I was on a horrible weight weenie jag and switched from the stock rim tape on my Reynolds Alta Race wheels to velo plugs. I had the stock tape at 28 grams and the velo plugs at 7 grams. So for me it was 20, not 30. They work perfectly for me, fwiw. I keep a couple spares in with my tool kit in case I lose one while changing a tire ... but it's never happened.
