Review (3/5): Try it out, but with a grain of salt
So, I ordered this product and did receive it in a timely manner. I’m currently on the last packet of it and I have to say, it’s okay. What I mean by okay is it’s packaged well and seems legitimate but, it didn’t get shipped cold and it literally says on the box to keep it refrigerated. Also, I’ve been consistently using the packs.. one every other day and leaving it on for 25-30 minutes, but it hasn’t noticeably whitened my teeth. Maybe it’s a placebo effect to see a “huge difference” but I honestly don’t notice any big difference in teeth coloration. I didn’t have any sensitivity really as other posters have stated. Then again, this product will work differently on everyone’s teeth as far as color/sensitivity so keep that in mind. I wouldn’t say this product didn’t completely work, but for me personally, I would say spend the extra $100 or however much to get your teeth whitened at a dental office.
