The Pulsator IV is the only machine on the market with a 5-Year Warranty! It has three modes of operation; manual, program, and learn, that allows the operator complete control during the ejaculation process. The complete package comes with the Pulsator IV, charger, one probe (your choice of size), 2 probe cords, scrotal tape, semen collection handle, 100 disposable cones, 100 disposable vials, carrying case, and instructions. Beginning 11-15-16 we have a new and improved probe cord connection on all Pulsator IV machines. The new connection is more water-proof, will give better connectivity and improved longevity! All Pulsator IV units sold and shipped on or after 11-15-16 will have a Serial Number ending with "B" designation. When calling to order probe cords, or with questions about your machine please, make sure to let us know you have a "B" machine so we can get you the right product and information. Also, beginning 11-15-16 with "B" serial numbers, we have eliminated the power supply connector on the machine and subsequently, the power supply is not part of the complete set.
