Frequently Asked Questions About Electro Equipment
What is an e-stim humbler?
A humbler is a CBT restraint that traps the testicles behind the thighs so the wearer must stay bent forward or kneeling. This Exposed model adds e-stim: two in-line adapters let you connect leads and run electric current through the device for combined restraint and electrostimulation.
How does the humbler lock work?
The Exposed E-Stim Humbler has a built-in locking mechanism and includes two keys. Unlock it to open the hinged halves, which swing up to 90 degrees to ease the testicles into position. Close it slowly, adjusting as needed to prevent pinching, and the lock engages once it returns to the closed position.
Is a power box included?
No, the power box is not included. The humbler accepts 4mm banana unipolar leads into its metal connection points, and pin-to-banana adapters can be used if your leads have 2mm pins. Connect the leads to your own e-stim power box and adjust the intensity and mode using that box's controls.
What is the humbler made of?
The Exposed E-Stim Wooden Humbler is built from smooth wood with brass, steel, stainless steel, and plastic hardware in a black finish. The wood construction is durable and safe for intense sessions, and the metal parts handle the locking mechanism and the e-stim connection points.
How do you use the e-stim feature safely?
Keep e-stim below the waist and away from the heart, and never use it if you or your partner has a heart condition, a pacemaker, or epilepsy. Start your power box on its lowest setting, increase slowly, and stop if the current feels painful. Position the testicles carefully to avoid pinching.
What size is the Exposed humbler?
The Exposed E-Stim Wooden Humbler measures 15.2 inches in overall length and 2.3 inches in height, with a scrotum hole 1.7 inches wide and 0.7 inches high. The hinged opening swings up to 90 degrees, giving room to pull the testicles into position before locking it closed.
