This is used for hands free stimulation of your penis. Either by you or your partner. With the length of the toy, it really only stimulates the head of your penis. If you can call it stimulation, but we will get to that a little latter on. You need to lube up your penis and the inside of the cobra libre, insert your penis and turn on the toy. You can adjust the power of the vibrations to your suit. I suggest using this toy only when you have the house alone, since it is very loud when set on high.

This toy is made from a combination of silicone and plastic. The body of the toy is made from plastic. The portion of the toy that your penis is inserted into is made from silicone. The buttons are in the plastic portion, and they seem to be waterproof (though I can not find any info about how waterproof this is) as they are seamless. The silicone portion has very little give to it. The bottom portion is up against the plastic, giving it a very hard unforgiving feel. The upper portion has a lot of flexibility to it, but it is not enough to make it comfortable.

There is no texture to the plastic or the silicone. It is smooth and almost seamless. There are a few seams in the plastic portion. The silicone is seamless. There was no detectable smell to this when I opened up the package.

The shape is a hard one to describe. You can see the outside shape from the product picture. The inside shape is much harder to describe. The opening is huge, but very shallow. You only get about 1/2 inch of depth to the large opening, then it gets really narrow. The product page says this will fit a 1 1/2 inch diameter, but the inside diameter is less then 1 inch. This would not be a problem if it was flexible and the materiel had some give to it. But with the silicone attached directly to the plastic, there is no where for the silicone to flex to.

With the interior shape and size, I could only get my penis head in and still be comfortable. I expected to get more of my member in for the sticker price on this. It is just too narrow and rigid for anything more then the average sized penis head to fit inside.

I guess this is pretty easy to hid, since it does not really look like a sex toy. I don't really know what it looks like to tell you the truth.

This is where it gets more difficult to use. There are three buttons on this guy. One that turns it on, and then two that change the intensity of the vibrations. You only need to touch the power on button to turn it on. But it is next to impossible to turn it off. You have to hold the button for what feels like a minute. It does not really make much sense to me. Just bump the on button and it is on and running. But you have to camp on the button to turn it off. Not very helpful when you have to turn it off in a hurry because the noise has brought some unwanted attention to your bedroom door.

The "volume" buttons are also difficult to adjust. Sometimes you only need to touch them and the "volume" changes, other times you have to keep pushing the button and playing with it to make it work. There seems to be some patterns, but every time I try to find them they seem to be different. So I do not know if they are a figment of my imagination or real. I also have not found any information about the different vibrations settings in the booklet.

The charger uses a magnetic to connect to the cobra. I had about a 50/50 chance of the charger staying on the fun factory logo and the charging light coming on. And then when I would sit it down, the magnetic would get bumped and the light would go off. It is a kind of awkward setup. The toy does not sit right for the charger to stay put when it is sat down on the counter.
The power of the vibrations go from non-existent to numbing. Non of them did anything for me, but make my penis numb. Plus they are called volume buttons because the cobra is so loud you can hear it through a closed door. It is really loud. I can leave it running on the bed, walk out of the room and close the door and still be able to hear it across the room adjacent to my bedroom.

The buttons are just poorly designed. They are touchy sometimes, and nonworking other times. It is enough to make you want to throw this against the wall in frustration.

Clean you new cobra before its first use and after each use with some warm water and mild soap. I would not soak this in the sink, as there is a battery and it is not stated as being waterproof. I have washed mine under running water. It has worked after each wash with no problems. Make sure to dry it off before storing it.

I recommend using only water based lubes with this. As silicone based lubes can cause damage to silicone.

This came packaged in a cardboard box with a large window showcasing the cobra. The cobra is in-cased in a plastic inner case, along with instruction booklets and sample lube packets. The plastic inner case works well for storage. It will keep your cobra dust free and ready for its next encounter with your penis. This also comes with a separate charger. I am not sure why it was not included in the cobra case, maybe it is a extra and not included with fun factory rechargeable toys. But the charger is in a smaller cardboard box. I did not keep that box, it was not really good for anything but the shipping.

The instruction booklet has a lot of info included inside. It is also written in about every language known to man. It took me awhile to find one that I spoke.

I tried this toy about a dozen times. I only had it work once. And that was because we where also including some anal play. They cobra by itself just does not do enough to bring me any where close to the big O. In fact, my penis would hurt long before it even came close to giving me any pleasure. I am about average size, so I would have thought that this toy would fit a guy like me. But it was just way too narrow inside, towards the end of the insertable portion. This was a huge disappointment for me. I was expecting so much more from a $140 toy. When I saw it I was so excited, because there just are not enough high end toys for guys. And it was hands free, leaving my hands free to play with other things. This just is a bad execution of a good design. A few changes and they could have a killer hands free toy just for us guys. Make the insertable portion longer and more flexible, kind of like a masturbation sleeve. Fix the buttons and make them easier to use and more consistent, so you are not fighting with them to turn it off or change the settings. And try to make it less noisy. This thing is way too loud. If you have roommates, or still live at home; this thing will wake them up on any setting higher then the medium setting.
