Cupid kiss can be used for both vaginal and clitoral stimulation. Although intended for G-spot stimulation, penetration never did much for me, so I used it more on my clit. Thanks to the material and texture, it is very easy to hold in place, and comfortable to hold for long periods of time.
Its vibrations aren't as strong as I would have liked it to be, but the multi-speed settings more than made up for that. Instead of bringing me to orgasm quickly, the different speed settings can be used to slowly build up your arousal.
Use this when you have a bit of time. If you want, you can combine it with toys with stronger vibrations as it really does intensify the experience.
I've found that it is indeed waterproof. I have used it in the shower on multiple occasions and have never gotten water in the battery compartment.

There was no smell when it came out of the box. The material is smooth, rubbery, and squishy; unfortunately, oftentimes it is too pliable for my liking. The material does seem to have the tendency to pick up dust and lint so be sure to clean it well and store it in a clean place. The texture is quite basic; it has ridges but I felt that it neither detracted from nor added to my experience.

The color was cute, and I definitely appreciated the sleek, smooth design. The battery cap is very pretty as well. All in all, it was very eye-pleasing.
I feel like it was well built. It's very waterproof and seems pretty sturdy.
The Cupid was definitely a lot thicker than I expected it to be. I'm a small girl, so even with lube I had some trouble getting it in. It didn't really matter though, because I prefer it for clitoral stimulation.
Because it's made for g-spot stimulation, I feel like it could have been curved slightly more. But like I said, I don't use it much for penetration.
Clearly, it is not discreetly designed, nor is it the quietest toy. You can probably use it under covers, but some buzzing would still be audible. I wouldn't take it out of the house.

The Cupid is operated by a single button at the bottom of the toy. It was a tad hard to press; and when you really get into it, the last thing you want to do is fumble around for a good while just to make the speed faster. The control could have been more accessible, but it's not a major problem.
I loved the multi-speed controls. These are definitely the highlight of the toy.
There's slow, which I hardly use because I honestly don't feel anything from it.
Medium - I love this setting because it hits me just right. It's not faster, hard, and strong. Instead it just lulls me and brings me slowly to orgasm. Love it.
Fast - This setting doesn't do much for clitoral stimulation, especially if you use the tip of it to stimulate your clit. It was too loud and numbing for me to use vaginally as well.

Then my favorites: the variation speeds, where it starts and slow and gradually goes faster. Just when it's fast enough and you think you're going to come, it stops and you're left wanting more. And then it starts again. These send little jolts and pulses to you and can really bring you over the edge if you're aroused.

I feel that it's easy enough to care for. I just wash it off with soap and wipe it down with the edenfantasy wipes that you can get with every order. I keep it in a box with my other toys in a cool place. Although it's well made enough, I'm not sure if it can really withstand the heat of Socal in the summer.
It's a bit of a lint-gatherer so make sure you clean it well before every use!
