Before settling down to try out my new toy, I charged it fully, then took it off to the bathroom sink for a quick wash. I clean my toys with toy cleaner and rinse with warm water, but mild soap and water would also suffice. Since the silicone attachments don't contain any mechanical parts, you could boil those if you felt the need to sterilize them (not sure I'd put them in the dishwasher, just because they're so small). You can also wash them with alcohol or a 5-10% bleach solution to sanitize them. However, the Vita itself should not be boiled (it would ruin its mechanics), and since the "business end" is plastic (which is slightly porous), I'd advise sticking to toy cleaner and/or soap and water (also, if you intend to share this toy with someone to whom you are not already fluid-bonded, it's advisable to either have them use it with the silicone attachments, which can be easily sterilize, ruining it, and you can also take it with you in the shower, bath, pool, etc.
Once my new toy was charged and cleaned, I settled back on my bed with my new friend, propped up on a pile of pillows in a sort of half-seated missionary position (my preferred and most comfortable position when I'm playing with myself), I tried out the lowest setting without the attachments, just to see what it felt like. YOWZA, does this little guy pack a punch! I actually found that even on the lowest setting, it was a little too intense for my clit right off the bat, so next I tried the tongue-like attachment on the lowest setting, and that felt much better. While the vibrations travel well through the silicone and the flexible tongue sort of flickers and oscillates, the squish of the silicone does seem to cushion the vibrations just enough to make for a slightly gentler experience, which was a relief (I need strong clitoral stimulation to actually reach orgasm, but I can't handle super intense vibration right out of the gate, I need to sort of work my way up to it). The mini-tongue felt amazing! It was just the right size to hit the spot perfectly, and I found that I really enjoyed the feeling of the small nubs and ridges. I could feel them just enough to appreciate them.
I swapped out for the bunny attachment, to see how that felt. The quivering ears felt wonderful on my lady bits, although I found that the way the ears are splayed so wide apart made it a little difficult to get them to "hug" my clit. I had better luck just angling one ear on my clit, or by positioning the bunny's face on my clit and having the ears tickle the area near my vagina opening. I also found that the bunny attachment felt great on other parts of my body, like my nipples, inner thighs, stomach, perineum, and the outside of my anus. There really wasn't any part of my body that couldn't be teased and pleased by those soft, trembling ears! Although I don't currently have anyone to play with, I can see this being a great couple's toy, with the way you could sensually tease any part of your lover's body.
Ultimately, however, I decided that while the bunny attachment was awesome for other body parts, the tongue-like attachment is what my clit liked best, so I swapped back out for that attachment and decided to try for an orgasm. To help things along, I pulled up a sexy story on my phone, and went back and forth between using the Vita to tease my nipples and my clit with the oscillating mini-tongue. Within a few minutes, I was quite aroused, so I abandoned my nipples and my phone and focused the tip of the tongue on my clit. I dragged it across my vaginal opening a few times to spread some of my girly juice over my clitoris and vulva, then placed the tongue back on my clit and began to slowly ramp up the intensity. It felt lovely, but it was also making me crave some internal stimulation, so I pulled out my Dual Density Silicone Dildo and added it to the party. I didn't have any trouble positioning the Vita with a dildo in my vagina, and I found it very easy to manipulate both toys. Holding the Vita to my clit while thrusting that soft, realistic-feeling dildo in my pussy felt amazing, and it only took a minute or two before I felt a climax wash over me.
I did notice that the vibrations of the Vita tend to get bogged down a little when you press it too firmly against your body, so if you're the sort of person who needs pressure on your clit to cum, this toy probably wouldn't be the best option for you. It seems to work best (with or without attachments) when you just hold it lightly to the area you want to stimulate.
