The Armor Piercing Speeding Bullet is intended for use on the clitoris and outer physical erogenous zones (vulva, testicles, perineum-careful!, nipples, etc). I think it would be best appreciated by those who enjoy strong vibrations to their clitoris, who prefer extra external stimulation either alone during masturbation or with a partner during foreplay or intercourse. It's very small, even smaller than I expected from the description, and very discreet. Because of its length/girth, I would exercise quite a bit of caution when using this bullet near the anus as well as the entrance of the vagina. I found the Armor Piercing Bullet very powerful despite its size! It brought me to orgasm in less than 10 minutes, which is quite a feat. This bullet can be used with pressure, pressed against the clit, and continue to vibrate just as powerfully. I found the shape of the Armor Piercing Speeding Bullet to be just perfect, the slight curve in the middle of the bullet perfectly surrounded my clitoris and surrounding area, bringing intense vibrations and an intense orgasm!

I have only used this bullet alone, but I am anticipating using it with my partner in the (very) near future. Because it is so small, the Armor Piercing Speeding Bullet will not get in the way during intercourse, and it is not particularly noisy/disruptive either. The vibrations are pretty powerful, so I could see my partner feeling it while using it on myself during intercourse. More fun for the both of us! This is quickly becoming my go-to sex toy.

Evolved does say this is a waterproof bullet, but I have my doubts & have read many other reviews stating that it is NOT fully waterproof. The battery compartment twists on and off, and it does not appear as secure to me as a waterproof toy should be to ensure a seal from leakage..

The Armor Piercing Bullet is made of velvety smooth plastic material. I did not notice much of a scent at all, which is really quite a relief (I think that's one of the things that can really ruin a sex-toy's first impression). I did notice I was able to scratch the surface of the bullet and see a mark from my nail, but after lightly rubbing my finger over the scratch, it disappeared quickly. It's a hard material, but it is very soft and velvety as well (similar to a silicone type of feeling, with more sturdiness/firmness). If rubbed against the labia, without lubrication, it catches slightly but not in an uncomfortable way. It gives a nice tension, a slight pull. Upon lubrication, it glides easily over surfaces and is very enjoyable.
It is relatively simple to clean as well, though I am told that plastic is not able to be completely sterilized...

I love the shape & design of the Armor Piercing bullet, it is very svelte and tiny. It's small size makes it ideal for travel, if you make sure to take out those batteries! It can also be used in conjunction with other toys, like a dildo or internal vibrator, without getting in the way. It can also be used with a partner without interrupting the flow of the moment.
It is tapered in its shape, so that it has a little waistline. This allows for the bullet to be pressed around the clitoris, above and below, or I suppose like a rainbow side to side as well. Yes, I essentially just said it is the rainbow to my clitoris. I personally like this much better than a flat surface, because I may be more sensitive in that way when pressure is applied (and I am a woman who needs pressure to orgasm). The Armor Piercing bullet also has a more distinct, pinpointed head. This is nice to use almost like a pen to the surface of my labia, and can allow a more direct, precise sensation when needed to find that special spot.

I think it is a good size for both beginners and the more experienced toy-connoisseurs; I believe a bullet is a great toy for everyone!
As far as hiding this fella', I don't really have to hide my toys. I live alone! And guests aren't generally going through my things.. But the bullet is small enough to be well hidden, if need be. I personally would worry about not being able to find it again! I've put the Armor Piercing bullet in the little inside pocket of my purse, and it fits well & hasn't turned on (I put the battery insert in it, rather than removing the little watch batteries entirely).

This bullet does have five functions! They are accessible through a nice little button at the bottom of the bullet. Personally, the amount of pressure to click that button and breeze through the functions was perfect for me. Not too light or too difficult! I suppose it can be a bit tricky if you're very well lubricated and slippery, because it is a small toy and it's entire body is getting used during play... But so far, I haven't had any troubles.

The vibrations are pretty much all over, which is a bit annoying to me, because I don't like to feel vibrations up my fingers and hand while holding a toy. But I suppose it's the sacrifice I am willing to make for a fun little toy such as the Armor Piercing bullet.
Now, onto the functions.

1. "Low" constant vibrations: very intense for a 'low' setting, I enjoy this one just as much as the higher setting!
2. "High" constant vibrations: wonderfully intense, powerful vibrations. Gets the job DONE.
3. Steady buzzes of vibration, spaced apart evenly apart: I didn't really care for this one, it felt 'boring' to my clitoris.
4. Even quicker, shorter vibrations with less space in between buzzing: I liked this more than #3, but less than the others. I'd use this setting to slowly build up, and then use the other constant vibrations to finish. Personally!
5. What reminds me of a phone vibrating, only more intense vibrations. I follow it by saying "one TWOOOO.. one TWOOOOO.. one TWOOO" I'm really scientific in my observations, I know: I liked this one, though I didn't expect to like the setting very much. It was definitely 'interesting' enough for my clitoris to pay attention, drawing on the second burst, wanting more, then getting the first teasingly short buzz...

As far as sound goes, it's not silent, but for the power of its vibrations I consider the Armor Piercing bullet to be pretty discreet. I can use it without wondering if my partner's roommate can hear it down the hall. Under a blanket, it's definitely a discreet toy.

This toy is easy to care for. A quick wash down in antibacterial soap & water (batteries removed to be safe), or by use of rubbing alcohol wipes, and it's good to go.
Because it is made of plastic, it is compatible with any lubricant. This makes it a very convenient toy if you're particular about using a specific kind of lubrication.

In terms of storing the Armor Piercing, I've kept it in its little box. It's so small, I don't have too much issue with doing this. I have also thrown it into the little inside pocket of my purse, as I mentioned before, and had no trouble with that either. I keep that pocket clean though, so maybe this is why I haven't found lint on the bullet yet..? I just wiped it with toilet paper, and my verdict is that this plastic is velvety but not the kind of velvety that picks up lint very easily.

The toy is packaged in a very small clear box, with some printed text about its usage right on the outside. It says the company's name in pink, and on the front it's in white outlined with black with artsy stamps of pink along the edges. Nothing too risque here, just a small discreet and convenient box. Inside it comes in a black tray, with 3 of the watch batteries resting underneath. Overall, it's pretty classy looking. And small!

I keep the packaging just to store the bullet but I may toss it in the future..
There was not an insert inside the box explaining how to use the Armor Piercing Speeding Bullet, which is something that makes me sad as a consumer. I like to read all the information that a company can give me. It makes me feel safer, more informed, etc. The outside of the box does state that it is an adult novelty, to be used as such, and should be used externally, etc.

I am finally content after purchasing an adult toy! This bullet hit its target perfectly, dead center. It's exactly what I needed to add to my small collection, and I am very excited to have found a bullet that will take me to orgasm however quickly or slowly I desire. I think it's perfectly designed, (shape & material -wise), and I am enthralled at how such a petite little bullet can pack such a powerful vibration! I am hoping to keep the Armor Piercing bullet in the top of my drawer for a long time coming...
