This bullet is small, discreet, powerful and especially great for clitoral stimulation. It also works well for nipple stimulation. I wouldn't recommend this one for anal use, though, since it is very small.
It can be used during foreplay or solo play and I think it will work well for practically everyone.
You can use this bullet anywhere you want, including the shower since it is waterproof!

The Crystal High Intensity Bullet is made of smooth plastic, which gives it an appearance similar to that of metal, and is adorned by six little crystals. The texture is very smooth which makes it perfect for clitoral stimulation. It can get a bit too slippery once lubricated, though. There's also no smell at all in this bullet, which is always a plus, nor does it have any taste.

The Crystal Bullet has six white crystals going around where the cap is located. There's also a rubber ring there that prevents water from entering the cap. I like the design of this bullet. It's simply, discreet and small. It is shaped as a bullet with a pointed tip, great for clitoral stimulation and pleasure.

As a small and discreet toy, it is easy to hide and transport. It will more than easily fit in a purse or wallet, for instance. Due to its shape, size and design, it's easy to manipulate this toy so it can definitely be used by beginners.

The problem with this bullet is that it takes N batteries, which can be difficult to find.

This toy is easy to use. All you have to do is press down the button to turn it on and hold that button down to increase the intensity of the vibrations. To turn it off, you press the button once more. It's all pretty easy! If you want to weaken the vibrations you have to turn the bullet off and then turn it back on, though.
When it comes to the speed settings, the first one is slow but nice, while the maximum setting is very intense and powerful. I personally enjoy the maximum setting immensely.

The vibrations are located throughout the entire length of the toy.

As for the noise, this bullet is surprisingly quiet. You can almost not hear it at its lowest setting. At its highest setting it can be heard if there's another person in the room with you, but it's not so loud it can be heard through a door.

This bullet is also waterproof. I had no problem what so ever using it in the shower, and even though I have never completely submersed it in water, I sometimes lie down in my bathtub while using this one and it still works perfectly. Be sure to tighten the cap carefully and as much as you can so no water gets inside the toy.

This one is an easy bullet to care for. I simply use warm water and anti-bacterial soap to clean it.

As for storage, you can keep this one practically anywhere, since it is so discreet. I keep mine in a small pouch.

When it comes to its compatibility with lubes, I don't think there's any problem there. It is compatible with most lubes and easy to use with other toys.

The Crystal Bullet comes in a plastic case that you can easily open and is vacuum sealed in plastic. Inside the plastic case there's a picture of the bullet and some printed instructions.

If you want, you can reuse the plastic case to store the toy, but I guess that wouldn't be too discreet.

This bullet definitely does it for me. It is powerful and intense and able to make me reach my orgasm easily.
The first time I used it, the high intensity was able to satisfy me fast and thoroughly.

The Crystal High Intensity Bullet has become my go-to bullet for when I want an intense, easy clitoral orgasm.
