What does the Boost button do? Boost is a shortcut to full power. During normal use you set vibration and suction to the levels you like. Press Boost at any moment and every function jumps straight to its highest setting, without stepping through speeds one at a time. It is meant for the final stretch, when you want a sudden rise in intensity. On this masturbator it acts on both the vibration and the suction together.
Jock 15X: suction, vibration and a Boost button
The Jock 15X is a big handheld machine, 10.7 inches long and 3.8 inches wide, with an ergonomic handle for a non-slip grip. A hard plastic case protects a soft, stretchy TPE sleeve lined with rows of nubs. Vibration has 3 speeds and 7 patterns. Suction has 3 speeds and 2 patterns. A Boost button pushes all of it to the top level at once.
The sleeve pulls out for washing and a clear cap covers the end to keep dust away. It charges with the magnetic USB cable supplied. It is rated IPX4, which means splash resistant only. The case is ABS plastic and silicone in black, orange and white.
Best for: For men who want the widest range of settings in the Jock stroker line and a toy they can hold by a handle. The 5.5 inch insertion length suits average sizes. Those who like to edge will get the most from Boost.

How to use
Charge the masturbator with the magnetic USB cable. Take off the clear cap and squeeze water-based lubricant into the sleeve. Slide in before you switch anything on, so you can feel the nubbed texture first. Then turn on the vibration and pick a speed or pattern, and add suction when you are ready. Hold the toy by its handle and stroke as you like. Press Boost when you want everything at full strength. Afterward, switch off, pull the sleeve out, wash it and let it air dry before putting it back in the case.

- Pull out the sleeve and wash it with warm water and mild soap, then let it air dry.
- The case is IPX4: wipe it clean and never submerge it, boil it or take it in the shower.

The facts list 3 speeds and 7 patterns of vibration, and 3 speeds and 2 patterns of suction. Those add up to 15 settings. On top of them there is the Boost button, which raises everything to maximum.
Is it waterproof?
Not fully. It is rated IPX4, so it tolerates splashes. The distributor states it cannot be taken in the shower or submerged. Remove the sleeve and wash that part separately with soap and water.

The 9X has 3 suction modes and 3 vibration speeds. The 15X adds 7 vibration patterns, 2 suction patterns, a handle and the Boost button, and it is longer at 10.7 inches. Both have a 5.5 inch insertion length.
How long is the sleeve?
The insertion length is 5.5 inches. The outer case is 10.7 inches long and 3.8 inches wide, so allow for that when you think about storage. The sleeve itself is removable for washing.
What lubricant should I use?
Water-based lubricant only. The sleeve is TPE, and the distributor specifies water-based lubricants for this toy. Squeeze some into the sleeve before you start and add more if it begins to feel dry.
