The Dr. Laura Berman Sina is a very standard vibrator from California Exotics. It is intended for use inside the vagina, on the clitoris and labia, around the nipples, or simply on any skin surface you choose. The Sina should not be used for anal play as it does not have a flared based. Sina is waterproof, so feel free to take it in the tub, shower, or pool with you.

Immediately upon taking Sina out of the box I felt like it was a very low quality toy. The plastic just had a cheap feel to it and when I screwed the end off/on it made a bit of a creaky noise.

Sina is made from PU coated plastic, which has a safety rating of 7 on Eden. It is latex and phthalates free. It is suitable for water and silicone based lube, and is very rigid with no give. I noticed a slight plastic odor and taste when examining Sina, but nothing off the charts. Sina is ribbed for pleasure, but unfortunately those ribs did not do anything for me due to her main body being so narrow. A beginner may get some good use out of this toy, but if you are experienced and have had sex, Sina may not offer up the goods if you need your vagina to have a nice full feeling.

Sina is a light lavender color with two bulbs, one on each end, and a long narrow body that is heavily ribbed. Like I mentioned before, this design may be good for beginners, but if you are looking for a toy to really fill you up and deliver vibrations deep into the walls of your vagina, Sina will not work. Additionally, Sina is very small; dimensions are as follows:
Length: 5 3/4"
Insertable length: 4"
Circumference: 3 3/4"
Diameter: 1"
Weight: 0.2 lb
I believe the one inch diameter is for the bulbs, which are much larger than the main body.

Due to Sina's size, hiding isn't much of an issue. Slip it in a drawer or under your pillow and you'll be fine. You can also travel safely with Sina with no risk of embarrassment from it coming alive in your bag; just make sure you take out the batteries beforehand.

Sina's controls are very simple to use. On the opposite bulb from the insertable one is a seam, and this is where you rotate to turn the vibrator on. I tried very hard to deduce if the "mult-speed" advertised on the box was true, but I really could only detect a very small difference in speeds. This is also very hard to get to, as there is no indication of where one speed starts and one speed stops on the rotating bulb. On this same side the bulb actually screws off, and this is where you insert the batteries.

The vibrations are mostly located in the bulb opposite the controls. I could not feel them as strong in the ribbed shaft. The Sina can also get very noisy. If you just hold up the toy and turn it on, I would put it at 2-3 bees. When you apply pressure to Sina by pressing it against your skin, it can easily shoot up to 4 bees. This took away from the sexiness for me to hear this loud, rumbling vibrator go up and down in noise like some sort of lawn mower.

Caring for Sina is very easy, simply wash with warm water and soap or wipe with a toy wipe when finished. Unfortunately, there are no storage accessories provided with this toy, but you could always put it back in the box or just keep it in a drawer if you wanted. As stated before, silicone and water based lubes are appropriate for the Sina due to it being made of plastic.

Packaging was very simple. Sina arrived in a small purple box with a great deal of writing on it. On the front is a picture of Sina and it is described as a satin finish, vibrating wand. There is also a small picture of Dr. Berman. On one of the side panels it gives a little information of Dr. Berman, saying she is a world-renowned sex and relationship expert who has shows that appear the the Oprah Winfrey Network. She is also a regular on The Dr. Oz Show, a contributor on Everyday Health, a New York Times best-selleing author, and a weekly columnist for the Chicago Sun Times. She has appeared on Fox News, CNN, and in The New York Times and USA Today, and in "every major woman's magazine." With quite the hefty resume I expected a better product, and am a little surprised that a woman like herself would allow her name to be on such a low quality product. The other panel just gives a little big of information about Sina, describing its appearance and function. The back lists several characteristics, such as it being body safe, waterproof, powerful, etc.
The only thing in the box is Sina, wrapped in plastic.







When you take Sina out of the plastic and unscrew the one bulb, there is a wrapped up piece of paper inside, I assume to protect the battery compartment. Dispose of this before putting in batteries.

I really felt like this toy was very low in quality and disappointing. It didn't feel sexy in my hands, it just felt like crappy piece of plastic. Its design fell short for me and unfortunately it wasn't a keeper.

After washing Sina with soap I decided to try it out. I put in two AAA batteries, not included, and turned it on. The vibrations were decent, and felt strong in my hand. When I inserted Sina I just wasn't impressed. The only vibration I could really feel was from the end bulb, and it wasn't very stimulating due to the small size of the bulb and the distraction from the rumbling. It felt okay as a clitoral vibrator, but honestly, I was so turned off by the toy and noise that it wasn't a very fun experience. The textured ribbing wasn't felt at all and was a complete waste in design.
