Go Smile On The Go Teeth Whitening Pen, Effective in 7 Days, Travel Friendly, Easy to Use, Beautiful White Smile, Natural Mint Flavor

I absolutely love this pen I only used it once at night one day and i saw results instantly I stopped using it bc I either lost all of them already sadly or I just forgot about them which is also bad bc I bought like three of these ... but someone with naturally stained teeth that runs in the family I saw wonders I’m not a big fan of mint or peppermint flavors but this one was alright especially bc you only have to keep it on for 20 mins

I really liked this. It was very easy to use and the flavour was great. The only thing I didn’t like, it’s hard to see how much is left. I will definitely buy this again.

This product slightly whitened my teeth but the twist up feature is really not very good. You have to turn, and turn and turn the dial before product appears and this is just not a very good value for the amount of product you get. Can't honestly recommend.

Worked great first time I used it. But not as well as I continued. I’m using it sporadically but guess you need to follow the directions and use 2x a day for 5 days to get better results. Very easy to use and doesn’t really have a taste to it.

I have used this product to whiten my teeth for years. This product is easy to use, and this vendor provides you with a quality product on time too. *****

Works great. Easy to use. This is my third time ordering the product.

Used as directed for over a week and no change. Not worth the money. Crest Whitestripes worked better.

I used this twice a day for 7 days with zero results.
