Material / Texture

The slimline is entirely smooth. When you run your fingers over it, You come in contact with no texture or uneven surface. There is texture to the slimline. It is in the center of the bullet. It has the R-O Slimline 150mm texture inside of an oval. When using it, you do not notice the texture. When you are looking at it, you do. The texture is not something You will notice when using it.

The slimline is made of plastic which is Non-porous and phthalate-free material with a firm, smooth textures. This makes it perfect for anyone with a latex allergy. Because it is plastic it can easily be cleaned with antibacterial soap and hot water, or by wiping down with rubbing alcohol.

The slimline is waterproof, so when cleaning you can fully submerge it without worry. You cannot boil it. The plastic does not have a smell, or any kind of taste. The lack of texture makes the slimline perfect for anyone. I did not mind the texture at all. The slimline does have a more pointed end, but the end is tapered so you do not have to worry about hurting your self, or scratching yourself.

Design / Shape / Size

I personally enjoyed the design. That was one of my reasons for ordering it. The slimline is thin and long. It is a larger form of a smaller bullet. The slimline can be used internally and externally. The slim line is a length of 5 3/4 and insertable length of 5 inches. It has a diameter of less than 1 inch.

The size makes it perfect for more both beginners and more advanced when using it externally. If your planning on using it internally, I would recommend it for someone who is a beginner. The only reason I would not recommend this for someone who is more advanced is because it is so thin. Unless, someone who is more advanced is looking for something like this. In a general setting, I would recommend this to each group of experience.

The slimline can be used clitoral, and when used for clit stimulation only. It is perfect and provides a powerful deal of sensation, and pure delight. When using it internally, You still feel an immense deal of the vibrations. The vibrations can be felt deep within, but it is not as strong when using to for clit stimulation. When using it internally with any lube it can make holding it slippery.

The length of the slimline has many advantages. You can angle it right for g-spot stimulation. Although it is not used for it, you can attempt. You cannot use this anally, so I would not recommend trying it, or attempt too. You can also use it for sensory play. You can run it along your outer, more sensitive areas.

It is extremely discreet looking. When having it laying around, it just look like a golden pin. It does not scream out vibrator. The discreetness of the slimline allows you to place it just anywhere. You can toss it into you bag, or you can put it into your top drawer. The design of the slimline allows you to carry it around without any problem.

    • Discreet look/design

Functions / Performance / Controls

The slimline is pretty basic, and the newest of the new can use this without a problem. The controls are easily located. The slimline only has one button, and when pressing down you do have to apply extra pressure when switching through the settings. This did annoy me, but it did not keep me from continuing to use it. The slimline does have a few different setting to suite everyones needs.

1. On
2. Medium (2 bees, 3vrooms)
3. High (2bees, 3vrooms)
4. Medium Pulsation (2 bees, 3vrooms)
5. High Fast pulsation(2 bees, 3vrooms)
6. High Quick pulsation (2 bees 3vrooms)
7. Off

When turning on the slimline all you have to do it press the button once. When you are, turning it off you just hold the button down for about 3 seconds for it to shut off. When turning off you have to press down. If, you do not then it will not turn off. When using it with lube, it can make turning it off a pain. You would have to remove it and press down.

When on any setting, weather it is a high or low one the vibrations are only genuinely felt from the middle down. The R-O engraving it in the middle of the bullet, so from the RO down is where the vibration are mostly felt. This leaves you with the rest of the bullet to use as a handle. This is a plus, because it does not give you itchy fingers.

The slimline is waterproof, so when using it in the bath or shower it is extremely quiet. You can not hear it when it is under water. You can not hear it with the shower running. So when using it in the silent bedroom. You can hear a faint, extremely faint noise. With the television on you do not hear a thing, which it perfect with roommate living.

When using it make sure that the battery is entirely closed. The slimline does have an o-ring. The O-ring is black, so if your slimline does not have one do not use it or contact customer care. The o-ring keep water, lube, and other bodily fluids from entering the battery compartment. If, for some reason, water does get into the battery compartment. Allow the slimline to thoroughly dry before trying it.

The product page says that the slimline runs on watch batteries. It does not run on watch batteries. The slimline run on two N batteries. This could be a problem because I've noticed that N batteries can be hard to find.

The package it comes in is a hard black box. I love the package it comes in, and it makes a lovely gift. You can give it to a best friend, sister, or whoever. At first they would most likely think your giving them a nicely package pen. The box does have a window, so you can see the toy without opening it. The casing is hard, so you can drop it or throw it and never have to worry about your toy.
When you turn the box over it has information nicely written in gold writing, with a black background.

The box has information such as,

-Longer lasting and deeply satisfying.
-Ideal for those hard to reach areas.
-5Pleasure settings.
-100% waterproof.
-Batteries included.

The box recommends using the package over and again. You can recycle the box if you do not plan on keeping it. The box recommends using the batteries before 2013. I was surprised to see that because I've never seen information like that on any other toy before. When you open the box, you will notice that the inside has a velvet plastic insert. It is very thin, and you can toss it if you do not plan on using it. Under the insert is a sheet on instructions, the instructions tell and show you how to inset the batteries.

I love the slimline. When I seen it on EF, I kinda got excited and could not wait for it to arrive. When it did, I had to order it. It was a different story when it got it home. I was a little disappointed. That was before actually using it. It was thinner than I had thought, and felt much weaker. I just not long ago tried the R-O 120mm. That one was AMAZING! and by far is my favorite bullet. So, I kind of had high expectations from this toy. When I turned it on, I had my mind set that this was not going to be a very good bullet.

I was way wrong.

When I first tried it, I almost did not do it. It was the slimline or something else. I just decided to give the slimline a try. In my hands, the vibrations did not feel that strong, but when placed on my clit it was AWSOME! I must admit I was terribly wrong. I'm glad to say that I was wrong. The vibrations were very steady and did not require me to keep moving it around, or finding the right position.

When inserting it was a breeze. The vibrations were not as strong when inserted. I kind of wish it was, but I'm happy to settle with it being perfect for clit stimulation. The size allows you to use it in different settings. You can use it alone, or with a partner. When using it during sex, it is perfect because it is so thin, and it does not get in the way. The only problem I have is that sometimes it can feel as though it is poking you. This can be a problem, but easily learned how to be avoided.

In the end, I enjoyed it more than I thought I would have.
