I absolutely love this little devise. I use it almost daily. There are two parts to use:
The hand part is great for sore hands and I also use it often on the back of my neck to help loosen my tight muscles.

The bullet can be inserted vaginally or anally. If you choose to use it anally, be extremely careful! The base on the bullet is very small. It does have a cord, but you should never pull on a cord as a way to remove a toy.

I would recommend this for anyone who wants to try something new, pushing limits, or even just use the hand held part for muscle help.

This is mainly plastic, but the actual electric parts are metal. It is very smooth all over. I couldn't smell anything at all. And as far as taste goes, there is a warning to not put it in your mouth, so sorry I can't help you with that part. Both parts are very hard/firm.

There were a few things that I feel should be different on the bullet part. For starters if it can be inserted up your bootie hole, why is the base so small? Then there's the crevices where the metal and plastic meet....not very smart for anything that can be inserted. I feel like I can't clean those out good enough since I'm guessing that I shouldn't use a wet brush on an electrical item. I also think that the bullet could be a little bigger, perhaps the size of the handheld part, since it only has a diameter of 1" and a insertable length of 2.75".

This is great for a hand held tens unit on tight muscles. I use it very often on my neck. As far as the bullet goes...umm wow. I absolutely love it! It feels like someone/something is thrusting deep inside you. And the higher you turn it the deeper it feels like they are going. I do use it way more vaginally, than anally since the small base kind of scares me.

You can use toy cleaning wipes on it. If you want to get into the crevices, you can use a wipe with a toothpick or some other sharp nonmetal object. You can use a condom with this also, so if you want to switch back and forth, you need to do switch condoms.

To store it I just put the bullet part in my toy bag. I tend to leave the handheld part in a side pocket in my purse. Like I said I use that part almost daily because it's great for sore hands.

Both metal and plastic are technically safe with all lubes. However, since silicone is an insulator I don't suggest using it with this toy. A good amount of any other lube is a great idea though to protect you against electrical burns.
