I am really unsure if anyone can help me with this but maybe. Sorry, if I seem ridiculous, I have never owned one before :/

This may be a really easy stupid question but...I ordered the Orgasmalicious Candy Heart and I cannot get the vibrator to work. I would say something must be wrong with it but I had ordered this one because I ordered the same product from a different website and ran it to the same issue and returned it thinking it was defective. Am I missing something? I have tried putting the batteries in several different ways and it does not work. If you have any suggestions that would be great because I am assuming there is a very low chance I ordered two of these, each from a different website, and have the same issue. I must be doing something wrong.

Any help is appreciated, thank you!
