I'm always a bit skeptical about vibe sets, just because they all claim to be powerful but quite a few don't turn out to be. This set surprised me as the vibrating toys all worked great and the lube did well which was surprising to me. Since it's colder out and my house isn't horribly warm, I noticed that the lube seems to be thicker which I attribute to the cold, though it could just be the lube. I'm guessing that if you get it warmed up, it'll thin out, but I liked being able to not worry about pouring out too much. (The cap twists off and you have to pour, no flip cap or anything like that). Unlike some lubes, this one didn't just run down my toys as soon as I put it on, which was great because I don't like having a giant mess of lube everywhere. Overall, I think this was a great set and I'm glad I ordered it. So far (after a month), the batteries are holding strong as well.
