The teeth whitening strips are really good but the water flosser is really poor. I can’t acted customer services the day after I received it, they replied asking for more info which I gave straight away and I am still yet to hear anything back a week later. I believe they’ve made a poor product that is not fit for purpose and customer service are now being deliberately awkward and intentionally not replying. For teeth whitening strips spotlight is fine but having been a user of water flossers for years (other brands), I can honestly say this is by far the worst I have ever used.
