Well worth it , works great!!, good buy. Try this product it makes ur teeth truly and noticeably whiter. Wasn't sure how well it was going to work but I'm very happy with the results!!

These are a good to use to maintain a pretty white smile. I do this set twice a year and it allows me to have pretty white teeth along with regular check ups and brushing at least 2 times a day.

I always feel like these just are okay. The cost isn't bad but do my teeth look whiter? Meh kinda? They do make my teeth slightly sensitive when using them.

These are life changing! there is no need to go to the dentist and spend hundreds on getting your teeth whitened. these work perfectly fine and fast! if I know I have an event coming up I just apply these to my teeth and see instant results!

Love these so much! They work wonders but it's a little pricey and i've tried cheaper brands and they work just as well but the crest ones are definitely worth the extra money. So just go with what you prefer spending.

Would not recommend. The product squished out the sides and tastes like mushy peroxide. It left my teeth feeling very sensitive. I didn't notice any difference in the color of my teeth.

I work to keep my teeth feeling healthy and would love to know of more products that work as well as this one because I always come back to these ones and this brand!

this did make my teeth hurt and sensitive but after a few days they were fine and it did work to whiten my teeth! the light definitely helps better then without the light

The best whitening strips i ever used. I saw results within a week. Make sure you dont leave them on for too long because they take enamel off of your teeth

If you're looking for a good whitening kit well this is the brand for you ! It whitens in a matter of minutes ! It lasts a long time too ! I've tried other brands but none worked like this one . I recommend everyone to purchase !
