If you are looking for not just an excellent bipolar E-Stim electrode, but also something that is going to feel substantial once inserted then the Small Torpedo may fit your needs.
With a smooth rounded head, grip rings on the base a satin finish – the Small Torpedo will be a great feature in anyone's electro toolbox. The electrode contacts are at the top and bottom of the electrode, providing excellent contact and a more natural feeling than some other manufacturer’s designs.
The Torpedo is machined from aircraft grade materials, and if well cared for, last for years. It can even be disassembled for cleaning and it is covered by a lifetime guarantee. The base is machined with a series of grip rings to help during insertion and extraction.
The Torpedo is fitted with 4mm sockets in the base and works well with the low profile connectors. This comes in a plastic storage tube.
