I placed the wrong order and was sent polanight and contacted happy smile to tell them that polanight is a terrible product to use and I always use happy smile own brand as it works better and i get no sensitivity with happy smile ow brand gel. The customer service staff were very happy to replace the item and they even sent me a few extra free gels inside. I dealt with Charlotte the office manager and she was very polite, friendly and offers me a first class customer care experience. I have told my family and friends to order from Happy Smiles. THANK YOU HAPPY SMILE. If only all companies could be so professional.
