Works like it’s suppose to.
I was told about GLO from my dentist’s assistant. So I ordered it and both me and my husband have been using it. I already used bleach trays on my teeth so I didn’t see as big a difference. Now my husbands teeth I could tell a difference with his. I’m not sorry I ordered it because unlike how bleach makes my teeth sensitive this does not. I would recommend this product.
