4mm Low Profile Adaptors

Low profile (90 degree) connectors are essential for use with toys that you intend to sit on, as sitting on ordinary (straight) connectors is uncomfortable and will quickly break the wires. Low profile connectors are hard to find, especially if you're looking for ones with insulation on everything except the pin itself (which is what we want for estim, to avoid unintended current paths).

If you're buying new cables then I'd probably recommend buying ones with built-in low profile connectors, but if you already have cables with straight connectors or if you want that type of cable for use with other electrodes then these adapters are ideal.

The only slight issue with them is that the strain relievers are very stiff. This means the wire can bend sharply where it exits the strain reliever rather than bending gently over the length of the strain reliever. Potentially this could reduce the life of the wire and this is the reason I've given four stars instead of five. That said, they're the only adapter of their kind that I've found for sale and they're better quality than anything most of us could make for ourselves, so I can still highly recommend them.

Haven't used yet but appear well made
