The Mantric Sysil:Edge is a strapless double dildo with some twists. The most obvious of these is literally a twist: After removing the silicone key you can adjust the angle between the giver's "pony" end and the getter's shaft. The Sysil's innovations don't end there, nor is this merely a gimmick, as it serves several useful purposes.

The most obvious of these purposes is that the wearer can vary how high their dildo points when it is inserted. The three choices for angle allow you to maximize comfort and stimulation for the getter in a wide range of different positions. Want strong G or P-spot stimulation in missionary? Swing the Sysil up to the top position. Doing the deed doggy style, and want a little more comfort? Let your dildo hang low on the bottom setting.

That isn't the only positive from the adjustable angle, as it also allows users to snug up the pony against the front of their vagina, increasing G-spot stimulation and also potentially making it easier to hold in the Sysil:Edge without a harness.

The innovations don't stop at the hinged junction, either. The other big advantage of the Sysil:Edge is a vibrator that really works. Yes, you heard me right: this vibrator stimulates both partners.

Located a couple of inches up the shaft of the dildo, the standard-sized silver bullet (equipped with a button that matches the dildo's color scheme, a nice touch) is mounted diagonally , protruding up into a half-inch tall curved "horn" on the dildo's top. From this location the vibrations travel down the entire length of the getter's end and are noticeable at the tip, much stronger than the vibrations on any other strapless double I've tried. The getter gets even better: the vibrator's "horn" is located perfectly to put the vibrations right up against the clit - and the vibrator is a mere 1/8" away from the edge of the horn. If the dildo is used to penetrate a woman vaginally then the other side of the "horn" can bump right up under her clit for a bit of extra fun as well. When you need to take out the vibrator another touch becomes evident: there's a ventilation hole at the tip of the horn so the vibrator doesn't become vacuum-locked in the dildo. A quick push on the top of the horn pops it out - no lube needed. Indeed you might not want to lube up the vibe, as that can cause it to slip out during use.

The 100% silicone dildo is completely non-realistic and finished in matte silicone with a few textured swirls running down the shaft. The giver's pony is designed to catch up against the inside of the body, making it a bit easier to retain than the Feeldoe's "PC-only" bulb. Unfortunately the lack of a well defined body bulge on the lower side of the giver's end may make the Sysil:Edge very difficult to retain if your body doesn't cooperate, but if it does the Sysil is a comfortable dildo to wear. Note that if you have problems try different angle settings, as some can work better than others.

The non-realistic design and pink/purple colors mean that the Sysil:Edge can be viewed as a more feminine dildo, a plus for some couples. While it may look feminine, the design doesn't shortchange stimulation. The stiff silicone shaft is curved and has a bump at the head to increase G/P-spot stimulation, and the texturing feels nice during use. Note that there is a seam running down the length of the dildo, and in my sample it was noticeable in use. During one particularly rough bout of play it even caused the briefest tinge of blood to appear, although a quick go over with nail clippers and a razor blade soon removed the seam.
