Blue, beautiful and pretty strong.

The RO-160mm certainly should not be called a bullet. When the product page first popped up, I was kinda excited. It advertised it as the largest bullet thus far. So, I felt as if I needed to have it. I ordered it the day it came out. I was so excited. When they say it is the largest bullet they actually mean it. It is basically a traditional vibrator, but it is called a bullet.

When you first receive the RO-160mm the first thing you notice is the size. I have two other RO bullets from rocks off, and they do not compare in size. It' noticeably larger than the other two that I own. The RO-160 is perfect for anyone. It does not matter your toy level. Someone who is a beginner from someone who has used toys for years would both have an enjoyable time wit this. It is perfect for solo play, or with a partner.

You can use it to stimulate most areas on the body. You can use it for some sensory play. You can use it for clit stimulation, and vaginal insertion. You cannot use it anally. I does not have a base nor is it long enough. You can use it during sexual intercourse to stimulate the clit. It has so many uses.

The RO-160mm is made entirely of plastic. According to about.com, Plastic is any synthetic or semi-synthetic organic polymer. While plastics may be made from just about any organic polymer, most industrial plastic is made from petrochemicals. Thermoplastics and thermosetting polymers are the two types of plastic.

Plastic non porous, and dose not carry an oder. You do not need to use a condom when sharing this toy, but you can if you want too. I recommended using a condom with every toy. Plastic does not have any type of taste either. Plastic a fun material because you can use any type of lube that you want.

With the RO-160mm being made of plastic, it is perfectly smooth. If you do not like texture, or do not mind of your toys do not have texture this is perfect for you. The lack of texture makes it perfect for beginners who are not sure, or who have never used anything with texture before. The lack of texture does not offer any extra stimulation.

Plastic is an unforgiving material. It does not bend on it is own, and you can not bend it. When using it be careful not to be too rough. You can cause some pain to the uterus, cervix or vaginal wall.

I personally love the shape of the RO-160mm. I just love bullets all together. The size and shape makes inserting, and removing smooth and easy. The bullet does come to a point. I would recommend being extremely careful because you can hurt yourself if you are not. Shape is perfect for beginners, and the more advanced. The size of the bullet is somewhat discreet. You could not hide it in conspicuous view, but you can put it under your pillow, or hide it in your bedside table.

When traveling you can place it into your bag without a problem. It is discreet enough to travel. You can place it into your bad, and people will not look at you wondering what you are carrying around. It is too large to put into your pocket. The bullet is not too large as I had stated before. It is a very thick toy, more than it is large. It does give you a slight full feeling when using it, but it is not too thick where it would make you uncomfortable.

The RO-160mm measurements are as followed.

From the measurements, you can tell that it has some pretty decent measurement. The size of the bullet allows it to sit nicely in your hand without causing any extra work. The length of the bullet makes for perfect partner play when it comes to mutual masturbation. It will allow your partner to reach all you sweet spots without becoming uncomfortable.

The RO-160mm is pretty straightforward to use. It is operated by one single push button that is at the bottom of the toy. To turn the toy on you just press down once and it will turn on, and to turn the bullet off you will just have to hold it down for a few seconds. The bullet has seven different setting. With so many different pattern setting, it will suit even the pickiest users.

One thing I can say about this toy is that it is not the quietest. This could be a problem for some. When used in a silent room, I know people can hear it though a closed door. When used in a room that has a television as a slightly high volume. You may not be able to hear it though a closed door, but you can hear it through the covers. The bullet is also waterproof, so you can take it into the bathtub. When used in the bathtub the vibrations are still as strong as when, not in the tub, but the vibrations have a deeper sound.

The vibrations are felt throughout the entire toy. This is my favorite part about this vibrator. I've had so many toys that the vibrations are mainly at one end of the toy. The vibrations also carry exceptionally deep when it is fully inserted.

The RO-160mm run on two double A batteries. The batteries are also included with the toy. This is perfect, because you do not have to run out and get a pair. I've used this toy about 4 times, and the batteries are still going strong. So it does not appear to me as a battery killer. I will say when screwing the bottom back onto the toy. Make sure that it is tightly on. If, you do not the toy, will not start. The vibrations are fairly strong. It's perfect for the average user.

Taking care of the RO-160mm is extremely easy. You can store it into your favorite toy box, or you can use the box that it came with. When placing the bullet into your toy box you do not have to worry about it interacting with any other items inside of your toy box. When cleaning you can use mild soap and water. You can also use your favorite toy cleaner. When washing, you can fully submerge it without any problems.

The RO-160mm came inside a genuinely lovely box. It came in the same box that most of the other RO bullets come inside. The package is perfect for gift giving if you are planning to do that. The top of the box does have a window so that you can see the toy without opening the box. The box is hard and will protect your toy, if you mistakenly drop it. The back of the box does have some information. It has information such as the batteries it uses, and the multiple functions. You can use the box for storage if you like. If you do choose too, the box is not large so it will not take up too much space. Inside the box, is a clear and purple shelf. The shelf has a molded cut out of the toy. You can choose to use the plastic if you want too, or you can just trash it.

I'd have to say I thoroughly enjoyed this bullet. Although I would not call it a bullet. It is kind of too large to be a bullet. When I seen on the page as it listed the largest bullet. I was not thinking it was going to be this large. Besides the size of the bullet you notice the color right off. The color is this beautiful deep royal blue. I do not own any toys that are this color, so it was pleasant to add this to my collection. I used it alone mostly. I've use it with my partner and he happen to enjoy it. I thought he would think it was too large, but he did not at all, so that was a terrific plus. The vibrations were strong and felt pretty deep. The first time I used it, I kid you not, I could feel the vibrations in the back of my neck. I do not know if that's odd, but that is how strong the vibrations are felt when used internally.
