Not worth it. See little to no results.
My mother bought me the glo teeth whitening kit for Christmas.. Sadly it doesn't work well and I did not see much if any results after 5 days. I have used the device 3 separate times for 5 days and never saw the result promised on the description. Extremely disappointed in this product. Might as well buy crest white strips and save some money. Wish I would have looked at more review before asking my mom for this.
