The Vortex entrance is the tightest part of the Insert with a diameter of diameter 0.4 inches. This is followed by four chambers that are 1.6 inches in length and have a varying diameter of 0.5 to 0.6 inches. Each chamber has spiraling ridges as inner texture.
The stimulation that this Insert produces is truly amazing. While sliding in and out of the FL you will feel an alternating tightness brought upon by the five spherical chambers. The Vortex’s’ strong suction effect adds to the experience.
The Vortex Fleshlight does not require a lot of lube, but the spiraling texture does make cleaning the sleeve more time intensive.
The Vortex is one of my favorite Inserts, and is also ranked as one of the Top Sellers at fleshlight.com. Whether you are an experienced user or new to Fleshlight, the Vortex will bring you to dizzying pleasure.
