Riddix has the worst service ever! They charged my account twice and i never got my money back. so a word to the wise; DON'T USE UR CREDIT CARD! In addition to that, the product is no good. It made the pest WORST! or very angry. Now they have a mind of their own, so thanks Riddix, for absolutely nothing! What a waste of money I'm telling you. My daughter could kill bugs better. I have never had so unfriendly service in my life so the real question is did any of the people on the Riddex team finish highschool? Probably not.
