Kegel8 Pro Sensor | Compatible with The Kegel8 Tight & Tone, Ultra, and Vitality Digital Pelvic Exercisers

This item description said it was compatible with earlier Kegel8 models without the need for a lead wire- and it was not possible to check that before ordering as description didn't include a picture of the connectors. It wasn't correct and when I contacted the vendor they told me all their probes now required a lead wire- and I had to spend a bit of time explaining that in that case, it wasn't compatible with the machines they'd listed. Eventually they agreed to send me a lead wire without further charge- and now it works as it should. As to the probe- I much prefer this type to the newer style. And I remain happy with my Kegel8 ultra machine, which with regular use is effective for me.
