For sale is a Wyco vibrator. It works fine, I plugged it into a GFCI outlet and it worked as well as any other vibrator. Comes from a bankrupt construction company. I am not sure of the model as the name plate is lost. It is definitely NOT Wyco model #993.
I have a few more vibrators for sale and also am liquidating a big pile of parts such as vibrator shafts, etc.
You can return it if you do not like it, within 5 days of receipt, but you have to pay for shipping both ways.
