When you buy a sex toy that comes with a 40-page instruction booklet, you know you're in for a treat. Granted part of the reason it's that long is it's written in several languages, but still.I got this because the lovely woman upon whom I have a crush lives in London, and when you're separated by 4,748 miles, you have to get creative to make things work. Part of the creativity we've had to exercise has involved installing new server infrastructure in the house and brushing up on open-source streaming video server software, so it was nice to find a turnkey gadget that allowed her to reach out and touch me without the need for fussing with Darwin Streaming Server or dynamic DNS configuration. The current state of the art in open source software is why we can't have nice things...but I digress.This is a lovely device. It's absolutely fantastic fun. The smartphone software is easy to use, though you need to register an account with Lovense to make use of it...such is the nature of our modern, interconnected world.While the Amazon description doesn't mention this, the control app included an alarm clock function. Let me say that again to let the magnificence sink in: The app includes an alarm clock function! I anticipate that making waking up in the morning a whole lot more interesting.The plug itself is quite well-designed and definitely stays put even when you're out and about. It's not silent, but it's a lot quieter than many other wearable toys I've used. In a normal environment like a restaurant, the sound it makes is not likely to be noticeable.It offers powerful vibrations, of a deep, raspy sort. I quite prefer this to the high buzzing of some other vibrating toys.It's covered in silicone, but it is not solid silicone all the way through; the electronic gubbins are inside a hard plastic shell beneath the silicone. For that reason, it's harder than pure silicone plugs. I was debating whether to get the small or large size. I'm glad I went with the small. If you're on the fence, I'd recommend going with the smaller size, simply because if you're accustomed to other toys the hardness of this one makes it feel a bit bigger than it is.The description advertises 1.5 to 2 hours of use. We get 2 or more, but that might be because my crush is a tease and likes to run it at low levels just to frustrate me. If it's not running at all, expect about a full day of standby power on one battery charge, which means if you're in, say, hypothetically speaking, just as a random example, the Pacific time zone, and your significant other is in London, and you wear it to bed, you might expect to be jolted out of your sleep at 4AM when your London partner is waking up for the morning. Just, you know, hypothetically speaking.All in all, this thing is quite lovely. Definitely worth the price. We've talked about getting one for her.
