The RO-150mm slimline bullet by Rocks-Off is a very unique vibrator. It is almost like a cross between a bullet and a traditional style vibrator. Like a bullet, it is great for clitoral stimulation especially for those who like pinpoint stimulation. It can be used vaginally as well but I found that to feel rather pokey and uncomfortable and it just didn't work well for me in that way. Others may find the RO-150mm to work better for them internally, especially for those who are intimidated by a thicker toy, but for me it just wasn't that great. The toy is not safe for anal use and would probably very uncomfortable to use in that way since the design that is engraved and would feel very scratchy. I think it could work well for both men and women for some light external stimulation. It would also be a nice toy for couples to use for foreplay.

The toy is made from phthalate-free plastic. Like most plastics, it it very rigid with no give at all to it. Plastic is very smooth and a little bit of lube will go a long way. Plastic is compatible with any type of lube. It is a shiny gold color that makes it look like it is made of metal.

The bullet is completely smooth except for in the middle of the toy where there is an engraving. While this looks nice, it actually feels pretty scratchy and uncomfortable. Because of the emblem I really don't like to use the toy for insertion. I mostly use the bottom 1/3 of the bullet so I can avoid contact with the engraved emblem.

I thought the design was very unique. It was almost like a cross between a bullet and a traditional style vibrator. It was a little awkward for me to use at first because of its design. I found it a little uncomfortable to use internally because it felt like I was being poked with a pen, but it may work well for others. It is probably not the best choice for those looking for g-spot stimulation. Once I got used to the shape it worked pretty well for clitoral stimulation. I think it could work very well for beginners and those who enjoy slimmer toys for insertion.

Sizewise it is pretty small. It is 6" long and less than an inch wide and is very light. It reminds me of a longer High Intensity Bullet so if you liked it, you will probably like this one as well.



As you an see it is about the same size as a sharpie



It is one of the more discreet toys I have seen. At first glance it simply looks like a pen, especially when it is in the box that it comes in. Someone would have to look at it more closely to find out what it really was. It would be a great toy for travel because it is so small and portable and would be easy to throw in a bag or purse.

The RO-150mm is very easy to operate. It has a button on the top and simply press it to turn it on and press again to cycle through the different settings. To turn off the vibrator hold the button down for a couple of seconds and it will turn itself off. There are 5 settings to choose from.

1. low steady vibrations
2. high steady vibrations
3. slow pulses
4. medium pulses
5. quick pulses

The vibrations are decently strong, but I would not consider this to be a powerhouse. The vibrations are pretty buzzy. They are concentrated in the tip of the toy, but they can still be felt pretty well throughout the toy.

The batteries occasionally rattle. When the batteries aren't rattling it is a pretty quiet toy probably 2 bees. However about half of the time I have used it the batteries have rattled inside the toy and it makes it a LOT louder and probably closer to 4 bees. I wouldn't feel safe using this toy if I had to worry about someone overhearing what I was doing and it is kind of unpredictable as to how loud it is going to be.

It is waterproof and has worked just fine in both the shower and the bathtub and no water has leaked inside. As long as the cap is screwed on tightly, there should be no problems using this toy in the water.

The RO-150mm slimline is an easy toy to take care of. It can be washed with soap and water or a toy cleaner, but it should not be cleaned with alcohol.

The RO-150 runs on 2 N batteries, why they opted for that rather than a more common sized battery is beyond me. There certainly would have been room for at least a AAA if not a AA battery. The instructions state that rechargable batteries should not be used in the toy, though it does not say why. Also it is a good idea to take the batteries out when the toy is not in use to preserve the life of the batteries.

There is also a warning about turning the vibrator off it begins to get warm as it may overheat. I haven't noticed it getting warm at all while use, but it is a good thing to keep in mind.

There's nothing special that needs to be kept in mind for this toy. It does come in a very nice box that is perfect storage, but it could also be kept in a drawer or toybox with other toys and shouldn't harm the RO-150mm.

The packaging was really neat in my opinion. It was packaged the way a lot of the high end pens are. The packaging makes for a luxurious look and would be great for storage or as a gift. It is clear on the top of the box making it easy to see inside. There is a paper with a set of instructions with information about caring for the vibrator and batteries.
