The item's booklet says the contact gel is included, but it was not sent with the Acupointer. I told Customer Service and they said "I would like to confirm that this item is not advertised as coming with contact gel. It seems that this item can be used with or without." I tried to use it without the gel and it did not work. Their statement is false, saying it is not advertised as coming with the contact gel because the booklet has it listed in their packing list. I have asked for a return label and they will not answer me.
