These products, really don’t work! My wife and I purchased the whitening pack and none of us can see any results after multiple use.Their customer service replied after 2 weeks stating that everyone has a different whitening journey and therefore they cannot guarantee results. Additionally they said that they don’t offer money back but they are happy to give me some advice on whitening routines. You never know, your whitening journey might be more successful than mine:D! It’s a SCAM basically!
