This is, hands down, the go-to dildo for both my girlfriend and myself, especially when we want it rough, fast, and in every imaginable position possible. When she straps on the Siren, its firmer silicone body makes it easy for her to control the dildo, and the dildo stays in place during all the contortions we happen to go through! The sharp curve and bulb at the tip makes it an amazing G-spot dildo (I squirt every time we use it), plus the length and width are enough to make me feel full, without any pain. Whenever my girlfriend thrusts the dildo into me through the harness, the dildo's wide base stimulates her clit. Therefore, coming together while she's penetrating me is one of our favorite aspects of using this toy. I literally cannot get tired of it.

Cleanup is extremely easy with the Siren: you can wash it with hot water and antibacterial soap between use, boil it, or run it through the dishwasher's top rack without soap. Although it's extremely lube-friendly, its texture feels smooth even if you're not using it with lube. Since this is a 100% silicone toy, you should NEVER use silicone lube on it. If you use a condom over the toy, it would make cleanup much easier.

Depending on the receiver's anatomy and preference, I recommend turning the dildo upside down during strap-on play for doggy style, so the dildo's tip is still angled towards the G-spot.

This is not a "realistic" toy, which is something I like quite a bit. My girlfriend and I do have a realistic dildo, but I often enjoy toys resembling abstract sculptures rather than those looking like flesh-and-blood appendages. Although the toy's silicone is very stiff, it's not completely hard and inflexible, making it an effective G-spot stimulator that would not cause pain during rough sex. It doesn't smell or taste like anything in particular, so this toy is also fun to use for strap-on blowjobs. This dildo's texture is incredibly smooth which enables me to focus on the sensation of its distinct shape, and it's great!

The Siren's shape is quite elegant, which I like. I also prefer that mine is in black, because the color is not as kitschy or cliché as hot pink, or lavender. Since my girlfriend is butch, she definitely likes a more gender-neutral color. This dildo's design is simple, but VERY effective.

This toy is best for long sessions involving a lot of hard penetration. It is both stiff and light enough to keep from jiggling or falling out while adjusting positions, which is nice. This dildo is very easy for my lady to control while she is wearing it, so we do not have to keep readjusting the toy, or the harness. I honestly can come for hours with this dildo.

Again, DO NOT use silicone lubes with silicone toys such as this dildo! We use a water-based lube and it works fine with this toy. This dildo is very condom compatible, which makes it good for sharing and reusing. It is very easy to clean this toy with toy cleaners, antibacterial soaps, by boiling, or in the dishwasher. Since the Siren is made of silicone, we store it in a plastic bag to keep dust and hair from accumulating on its surface.

The Siren came in a simple box and it made removing the toy very easy. However, the box is not great for long-term storage.

I never get tired of this toy. Although having a variety of other dildos are great, if for some unknown reason, I am only allowed to choose one dildo for the rest of my life, it will be this one.

This toy is extremely easy to use, and my girlfriend and I prefer using it for strap-on play. It is O-ring compatible and the ring keeps the dildo's wide base securely in place, making it easy to control. For my girlfriend, the dildo is like an extension of her body and its base stimulates her clit whenever she thrusts with the dildo. I have no problem taking the whole dildo inside of me, and I like using it for rougher sex.
