Use of this product resulted in little if any whitening. I definitely will not purchase again and intend to try Crest Whitening Strips.

very easy to use and really works.

Given the much lower special price and hugely positive reviews, I decided to try the product. The product comes in a very nice packaging and is very easy to use. However, after the full course of using the product twice a day after brushing my teeth and religiously not eating or drinking for 30 min after usage, I saw no results whatsoever. The teeth did not get lighter and the stains from tea and coffee did not disappear or even become less noticable. Moreover, my gums still became sensitive even though the product is advertised as not to cause gum irratation. I wouldn't recommend the product.

I really like the GOsmile kit. Keep in mind, I paid [$] for the kit, and I would not spend more than that. I have not tried any other form of whitening until this product. My girlfriend has used the crest advanced whitestrips and had similar results in terms of whitening. The GOSmile kit did a good job, I am 6 days through and significantly whiter. I liked that I could target specific teeth and avoid my gums. I found that it worked best if I used each ampoule twice. For example, I can cover my teeth using only half the liquid. I then reapply with the other half 20 mins later.To sum it up, if the kit is on sale for under 40 bucks, its a good option. If not, I'd try the advanced whitestrips first. I would not pay 90 for this kit.

it works great doesnt taste to harsh i used to use the crest strips but they were uncomfortable i stopped using them after just a couple days i began to notice a difference in my teeth after just a couple days

I have used a lot of teeth whitening products from the toothpastes to the strips. This product was like nothing I have used before. I love that it doesn't leave any residue or gel on your teeth, it's just a liquid that gets rubbed on. I have had sensitivity to some products in the past, with this I had no sensitivity at all! The tubes are so small you can take them with you anywhere. My favorite thing about them was that I could apply the product at night right before bed and not have to worry about removing anything, I could just go to sleep! They did an EXCELLENT job of whitening my teeth!!

i have tried everything from zoom bleaching to the trays that both hurt like hell.......go smile b one's are the best out there. my dentist couldn't even believe the results..........LOVE GO SMILE

My son and I wanted to try a tooth whitening system, so I decided to give this item a shot. Works very well, easy to use, no bad taste. Gets to hard to reach teeth, can concentrate on teeth that are stained more than others. My son drinks a lot of tea and his teeth were heavily stained and it worked very well. The price is right, so give it a try!

After exploring the different tooth whitening kit options available, I opted for the GoSmile B1 set: It was reasonably priced (comparatively, as it was on sale when I purchased it), and I appreciated the reviews that stated it wasn't harsh on sensitive teeth, nor did it have a strong flavor. I used the product as directed, in the morning and in the evening, through the entire course of treatment; at least an hour was between when I used the ampoule and when I would eat or drink again. Additionally, I would use them only after brushing + flossing my teeth (I didn't want any spottiness or uneven whitening). There was some mild sensitivity increase within the first week of use, but this subsided. Food and drink sensitivity was not discernibly exacerbated by the product. I was ultimately unimpressed: though the ampoules are easy and mess-free to use, the whitening they offered was mild, at best. Included in the set (which is in a well-designed, CD-case-sized box) are 20 ampoules. You squeeze the ampoule, until it cracks, and then apply the whitening solution to one's teeth. In the future, I will be using another brand -- even if application may be less convenient with a tray or strip, I have had better results with other types of whitening kits.

threw out my custom dental whiteneing trays, as this system is so user friendly. Best on the market
