In the time since I bought it, Lily has become pretty much my bff. When I locked myself in the library while writing my final papers, lily came with me. When I go to my parents' house for a weekend, lily comes with me. For these situations, Lily is really perfect because it's so tiny and rather quiet (except that it also makes a kinda high pitched noise which is irritating, but I imagine that in a few years my hearing will go enough that I can't hear it anymore), but that's really not all lily is good for. Not at all.
Before I got Lily I had been having a very hard time giving up the first vibrator I ever owned, a really basic slimline that worked every single time, even though I had "better" toys. The thing is that, though I love a lot of my other toys, I like how vibrations transfer through hard plastic much better than I like how they transfer through any other materials, and I like something with a bit of a rounded point on it for clitoral stimulation, which most of my other toys don't have. Lily has all of these things that I loved about my first vibrator, plus a whole lot more. For one thing it's really easy to use in combination with a dildo, which I love doing. It's small and light which means I can actually do something with the dildo while getting vibrations on my clit. For another it's got all of these vibrating patterns that, for me, work really well as a way of getting myself worked up before going for the gold. I'm particularly in love with the last setting, which is like a roller coaster, going from the lowest vibration level to the highest and then back down again in pretty quick order, I don't think there's much else that works quite so well as build up for a big orgasm.
Basically, Lily is pretty much everything I wanted in a go-to vibrator, and it will likely be my masturbatory BFF for a long time.
