Review on Advanced Silicone Sealant Box: WAT-755.00 - Ultimate Efficient Solution by Richard Payne

This thing has a big ball of silicone grease inside. Instead of dropping the o-ring, quickly twisting and pulling off the neatly greased o-ring, there is so much excess grease inside that you'll pull out a gooey mess. I found it easier to just put a little grease on my fingers and rub them gently over the o-ring to avoid excess grease. I won't return an item that cheap, but it won't be of much use either.
