Go SmileTeeth Whitening Stain Erasers, (28 Single-use, applicators), On-The-Go Instant Teeth Cleaning, removes Coffee, red Wine and Tea Residue from Teeth Before Stains Set in, Mint Flavored

I've been using Go Smile ampoules on and off since they came out in 2002. These "boosters" along with the "Super White" or whitening pens have always worked to whiten my teeth.I've seen complaints about them not whitening enough. It's important to keep in mind that it matters what your starting point is: if your teeth, like mine, are already fairly white, your result is going to be more subtle. And if you want your teeth whitened, say, 7 shades, go to a dentist to see if you're a candidate for a professional treatment. Considering how much that would cost, I think these give me plenty of bang for the buck. ( I don't have sensitive gums so that isn't an issue I need to worry about.)I'm really writing this review because of all the people complaining that they can't figure out how to use it, that nothing comes out. This is not the fault of the product: this is operator error. The directions clearly state that you need to pull the ampoule out of the cardboard tube, flip it so the brush end is sticking out, then squeeze the tube to crack the ampoule and push the serum through the brush. This keeps the product fresh and active. The design is ingenious, in my opinion.Just working well isn't enough: it has to be convenient. I don't know of any more convenient method unless maybe an elf comes in and cleans your teeth while you sleep. On second thought, that would be creepy. Unless it's Hermey; that would be great. (Yes, I just googled the spelling of his name.) I can't stand white strips. I've used Glo Science, which is excellent, but just not, you guessed it, convenient.So for every obsessive who will spend hours poring over Amazon reviews, I say this: If you're looking for something portable and easy to use, that will make your smile somewhat brighter and momentarily make your mask breath minty, if we're still wearing them when you're reading this, just stop scrolling and buy this and go do something more fun. You can always return it, right?

I need to order more- these are absolute magic!! While I have been working hard to save for my “smile makeover” because I work with high end clients but these have been heaven sent in the meantime!!!

Cam use it everyday and it's easy to use.

Product works very well.

These work better than strips. Brushed and flossed my teeth, followed directions and rubbed on teeth for 2 minutes and my teeth were noticeably whiter. Not bad tasting either. Ordered my hubby some.

I love how convenient these are to keep in my purse if I’m going from work and then somewhere else, I don’t have time to go home and do the whole get ready routine so I do love having that ability or being able to use them after I drink my coffee or something like that as for making my teeth any wider, I don’t think that they really have and that’s why I gave them the three star rating instead of four or five mostly because yes, they clean your teeth, but they don’t really whiten it

Love this stuff. Does not make my teeth sensitive, no flavor to it and is easy to use. I notice an instant outcome. Repeat customer.

6 of the 14 tubes were already cracked and dried up by the time I opened them. That will be the last time I ever purchase these. They are very expensive and I only received 8 usable tubes. Complete disappointment
