Really whitened and didn’t make my teeth sensitive or sore. I am definitely going to do the once a month little booster to keep my new white smile :)

I have used my Glo product about 6 times. I have noticed my teeth being whiter than before. It was noticeable in about 2-3 days. I bought an extra package of whiteners to have on hand. I do think that the whitener packets are a tad difficult to get all the gel out to use.

Easy and comfortable results for whiter teeth!

Was suspicious of this product at first because of the method it uses to dispense the product--it seemed wasteful. However, it's been several months of daily use and I'm still using the first one, even though I have since bought 2 more when on sale. More importantly, I substituted this product for a very elaborate regimen prescribed by my periodontist, who makes a slide of my bacterial residue every time I get my teeth cleaned. On my most recent visit, the dental hygienist declared, "You have a boring slide today." Just what I wanted to hear!! ECO is definitely effective and lasts a long time, despite its small container and seemingly overactive dispensing system.

I absolutely love this GLO to GO whitening pen! Very easy to use and I love that I can literally use it anywhere! No rinse required. My teeth look as good as new!!
