Used their at-home whitening kit across six weeks as directed. Results landed mid-range of expectations, roughly three shades lighter per the shade guide, less dramatic than promotional images but genuinely noticeable in photos. Sensitivity spiked during week two requiring rest days, common with peroxide products their instructions did warn about eventually. Kit contents felt complete and mouth trays moulded easily. Price undercuts dentist treatments substantially while outperforming supermarket strips. Manage expectations toward gradual improvement rather than transformation and it delivers acceptable value.
