These do work, as I feel a lot different when I use them. Got my power level reading from my third eye(my third eye is extremely weak, though) to shoot up to 1,000 through Rin, then used a few others and I felt very different feelings from performing each one. But I would definitely recommend that a few other people try these, cause my experience may differentiate from yours.
