This is a great-looking stroker, I must admit. The way that this "Endurance Trainer" is designed is both functional and simple. The packaging has a good size picture of what it looks like all put together.
This stroker adds a unique but simple grip device that lets the user adjust the pressure to their liking. It is a fantastic option in my opinion. At the smaller end of the case is the airtight end-cap that will provide either more or less suction to fit your desire as well. The sleeve insert is made from ULTRASKYN so be sure to use a water-based lube.
In the end this is a very sleek looking stroker that functions exactly like it should. I would definitely recommend this.
