Dr. Laura Berman Sina - traditional vibrator by Cal Exotics - review by Madame Z

Add resource

Intimate basics says it all

I can say clearly for myself that I was not entirely impressed with the toy due to the size and low vibrations I could get over one of those features if the other was there to take its place.
I do like toys that can be utilized in water so that was a nice feature, though over all, this one will probably not get much use from me.
Feels nice
water safe
easy to use
Weak vibrations
Rating by reviewer:
extremely useful review


The Sina is a toy meant for internal and external use. This vibrator twists to turn it on and to turn up the vibrations. It has a satin finish and feels quite smooth to the touch. It also has a ribbed center for additional internal stimulation.

Material / Texture

The Sina is made out of ABS with a PU Cote which is what gives it its soft and satiny feel.

It has almost no smell as well as no taste to it.

The smooth feel of it on the body is very nice. Internally the added ribs were pleasurable.

The texture is good, in my opinion, for beginners as well as advanced users.
    • No odor
    • Rigid
    • Smooth

Design / Shape / Size

The design is quite user friendly. Two soft founded tips with a ribbed center.

As I said, it is meant for use internally as well as externally. The packaging states that it is used to stimulate the clit, vagina, labia or perineum as well as internal use for vibrating pleasures. For me, it did decently at its suggested uses.

Externally, the design would have worked much better for me had the vibrations been more intense. As I said, the low to high feature did not seem to make a noticeable difference for me thus it was not as pleasurable as it could have been.

Internally it felt quite nice. Soft and smooth yet with the nice ribbed length. But it just wasn't thick enough for my liking.

It is a perfect fit for a beginner. The size and shape is not intimidating for those that are new to toys and are looking for something to try. But I am sure that for advanced users this may not be to their liking.

I feel this is definitely a toy that is discreet enough and suitable for travel.

Functions / Performance / Controls

The vibrations did not seem to change much from the lower setting up to the higher setting. It was just not quite enough for me in that regard but would work well for others I am sure.

The stimulating end houses the vibrator.

The vibrations coupled with the internal use I think is probably the best use. Due to the low vibrations and shape for me the external use was not optimal. Though I will note it was comfortable to hold ans was not awkward at all. It just wasn't pleasurable enough for me in that sense.

I am not a fan of the controls on this device. Though there was little difference in the low to high options the end was so smooth it was hard to keep track of where the twisting section ended and the rest of the device began.

The toy was a bit on the noisy side for me. Without a blanket it was quite loud and I could almost hear a high pitch sound that went along with it. Covered up I could still hear it fairly well.

As the description states, the item is waterproof. It functions the same in and out of the water, and when done so, it was found to be completely dry on the inside.

This, I would say, could be a good beginners toy. It is discreet enough looking for those that care. It is quite nice and soft to the touch and is not awkward.
    • Easy to use
    • Not enough variety
    • Weak

Care and Maintenance

This is a quick and easy toy to clean. Just a little mild soap and water and you are good to go.

You can use water-based lubricants with this toy.

    • Easy to clean
    • Easy to store


The box itself was long enough to accommodate the product and wide enough to accommodate three of them. There was no internal instructions or packing material to keep the product from moving around in the box.

All the instructions and information was on the outside of the box itself.

I suppose the package could be used to store the product, but I would rather not. The product itself could be stored better and save much more space with it not in the box.
    • Recyclable

Personal comments

Over all the toy was nice. It was simple, easy to use, had a nice feel to it and seems to be a good beginner toy.

I was less than impressed with the packaging information. You had to look all over the box for various information such as the type of material it was made out of, how to care for it, and what types of lubes were safe for it. That was all found at the bottom of the box in small writing.

These are things many people need to know and having the information tucked away I feel would turn some people off of purchasing the product.

    Great first review! I enjoyed reading this. Congrats on it! I have the Rhiannon, which is just a smaller version of this and I too felt the vibrations were lacking some for external use, but I enjoyed it so much using it internally! Thanks for sharing how this one worked for you.
