This is a great clit toy, though it can add vibration to any areas you like! Nipples, perineum, scrotum... really anywhere. I personally think it has the most effect on a clitoris, so it's probably best for women - but I have no experience with its effects on men... it could be quite effective (I have an idea about this - more on that later).
I personally love this toy because it fits in the pouch of my Spareparts 'Joque' Harness, and can stimulate either my or my partner's clit when wearing the strap-on. It's also great for the bath or shower (and so, by extension, for discreet fun when visiting friends or relatives, or for anywhere the bathroom is the only private space), and though I haven't tried it, a little fun when swimming (But don't lose it in the ocean! These things are pricey!).

"Little Perky", as the makers so affectionately named their Form 2, is made of high-grade silicone - one of the safest materials on the market. It has a very faint 'medical' smell when right under your nose, as most silicone toys do, and hardly any taste at all. It is smooth & very softly textured, with a little give. This feels amazing, especially when used with a very light pressure. There is a seam in the silicone where the two halves of the mold met - it is very slightly raised (we're talking half a millimeter, if that) and would give the faintest rough sensation on extremely sensitive nerve endings, but I never notice it. If you are a fan of smooth textures, as I am, this is likely a good bet for you.

It looks like a pop-art bunny! I find that ridiculously cute.
Once it's pressed against my clit, though, I don't find it cute at all - I'm too busy focusing on the power those dual-motors carry. Whooo! The 'bunny ears' each contain a separate motor, which work together to create powerful vibration from two sides. When sandwiched around the clit, this is just amazing. Since the legs of the clit travel down each side of the vulva, when both sides are stimulated it makes for some very happy women! It also really helps that the ears are flexible, so if needed you can press them together or apart for more or less sensation. Incredibly intelligent design - kudos JimmyJane.
The Form 2 is also useful for single-point sensation - when you rotate the vibe so only the tip of one ear makes contact, you can find some very focused vibrations. Likewise, for a more diffuse, less intense vibration, you can shift the contact point to the body of the vibe - the motors are at the tips of the ears so the further from the tips you get, the less intense it gets.

The biggest design perk for me is two-fold: 1) the small size (it fits in my palm) & 2) the wireless feature. Due to these two things, it fits inside my strap-on harness & can be used to stimulate the wearer. The body of it nestles against the wearer's vulva while the ears stimulate her clit. Plus, then the vibes travel down the dildo, which is a marvelous thing.

Now, I haven't tried this next idea, but it could work - hear me out: A cismale (a naturally born male, identifies as a man) who happens to have access to the Joque harness (or any other with a large enough pouch) could put it on around their penis, secure his scrotum inside the pouch, then put the Form 2 in the pouch to add stimulation to his balls, or rotate it so the vibes focus on his perineum. It's crazy, but it just might work! And then he'd have a vibrating cock, too. If any of y'all decide to try this, let me know how it goes.

This is a remarkably powerful vibrator, especially for its size! When I first picked one up & tried it on my hand, I was shocked. It has five intensity settings, which range from a relatively gentle vibe (though even that may be strong for some) to a super-hyped up buzz that left my fingertips tingling after just ten seconds of contact.
There are also four variation settings: steady vibration, a syncopated surge that seems to travel across the two ears, a thrumming pulse that simultaneously brings both ears' intensity from low to high, and a quick even pulse at a rate of about four pulses per second. The manual alludes to a secret fifth setting, and the first time I played with this I counted five settings, but since haven't been able to find it.
I just want to point out, real quick, that between the five intensity settings and the four variations (not to mention the variations you get through different placements and contact points!) there are twenty possible settings... Just saying.

It's much less noisy than its intense power suggests. In fact, I would be comfortable using this in a bedroom adjacent to... well, anyone I don't want to let know that I'm using it. Parents, roommates, employers... (wait, what?) Point is, it's quiet. Especially if you use it in the shower when the water is going. The only sound anyone nearby could hear would be your moans.

Speaking of which... The waterproof feature is phenomenal! It made me nervous the first time I used it submerged - I kept thinking it would short out or something, but it works just as well in water or out. This definitely expands the play possibilities, in a great way.

The control buttons are flush with the surface and intuitively placed. Vertically from the top: increase - decrease - change setting. On occasion I've changed setting when I meant to decrease intensity, and decreased intensity when I meant to increase it, but it's been no real problem.
The controls also have a very convenient travel setting so that even if a button gets depressed in transit, it won't start vibrating in your bag. Because nobody wants to miss a plane due to being investigated as a bomb threat.

As the Form 2 is silicone, you can wash it with warm, soapy water & air dry it. This is my recommended method, though you can technically run it through the dishwasher as well... even though it's waterproof, I personally would shy away from this method due to the vibe's electrical components. They are designed to be waterproof, but it would make me nervous to run an $135 toy through a dishwasher. Just as you would hand-wash an $135 cashmere sweater, hand-wash this little guy too. Just in case.

It's important, once washed, to wait until it is fully dry to store in the charging base (a small plastic square with a hollow containing two charging nodes - the vibe rests on these and charges through contact). Any water can corrode or short the electrical components in the base, and that's no fun for anyone.
I store mine upright in the base, whether it's plugged in to charge or not. It keeps it upright and dust-free, and is a classy way to display this little beauty.
For long-term storage, the manufacturers recommend you store it at partial or half charge.

Lastly, remember not to use this with silicone lubes - it will degrade the silicone & destroy the toy's smooth surface. With a gem like this one, that would a shame.
