Spooky2 has two types of hand cylinders: Spooky2 Stainless Hand Cylinders and Spooky2 Conductive Carbonized Rubber Hand Cylinders.
Spooky2 Conductive Carbonized Hand Cylinders are brilliant. They have a built-in resistance that makes the contact treatment more comfortable. They’re safe and good for long treatments. The only thing that these can’t do is be used with a foot bath.
However, Spooky2 Stainless Hand Cylinders are perfect for both regular contact mode and foot baths. They are made from top grade surgical stainless, avoiding the risk of heavy metal poisoning. Inferior products use aluminum or inferior, low-quality stainless. Spooky Stainless Hand Cylinders have been upgraded. They now have a plug attachment at the end. The TENS cable can be plugged straight in. Because surgical stainless is a stable alloy, these hand cylinders can be safely placed directly into a footpath.
In summary, Spooky2 Stainless Hand Cylinders are good for both foot baths and regular contact mode, but Spooky2 Conductive Carbonized Hand Cylinders are better suited for contact mode.
