Very good product if you are will to spend the money. Definitely does a great job whitening if you use as directed. But for the price I would rather just buy hydrogen peroxide to white my teeth with since it's literally the same thing but in liquid form and less than a dollar at most stores. Strips also make my teeth super sensitive.

I feel like this is definitely making a difference for my teeth BUT they are SO sensitive now. I only got to the second treatment and got super bad cold sensitivity - in the middle of winter no less. I will have to try again when its not so cold outside

I love the look these gave my teeth, noticeably whiter in no time if you're in a rush! They price is better than most. Although they definitely make my teeth noticeable sensitive to the point of pain! I love the instant results but be careful of over use!

I actually faithfully keep coming back to these white strips. I'm a pack a day smoker and I drink coffee all day long. Everytime I notice my teeth are looking dingey I use these strips for 3 or 4 days. My teeth are always back to white for a few months after that. They taste a little strange, but they stay on your teeth and the gooo rinses off easy when you take the strips out. I love these things. Totally reccomend.

These whitening strips are so amazing. They helped boost my confidence tremendously. After just one use I was already seeing changes. They can be harsh on the enamel of the teeth so I try to spread out my usage. They don't taste too chemically either!

These white strips work well and are really good at not falling off or sliding around while using. These products can be expensive depending on the type and how many you prefer. One thing that I would recommend is not using more the 3 days for sensitive teeth.

It's effective in whitening your teeth for sure! But I hate the fact that it made my teeth feel extremely sensitive, and I couldn't eat anything cold or hot without it irritating my teeth. The sensitivity lasts for a few days but it eventually goes away. However, if you are looking for a “at home” whitening solution and don't have sensitive teeth, then try it out

These definitely work! After a few uses, they do lighten your teeth a few shades. However, the taste and slimy feeling in your mouth while using them, combined with the sensitivity it lends you, as well as the price, really puts me off. I've been using Zimba whitening strips with no issue (they stick, are coconut based and they're cheap).

The BEST!!!! By far the best whitening product on the market right now! Super fast and affective for pearly white teeth! Helps with stains and doesn't require a lot of work or time. Lasting effect after just a few uses! Love these! They tend to be more on the expensive side but in my option are totally worth it! Definitely worth investing in!

I was pleasantly surprised by their kit. Very easy to use. Didn't make my mouth feel “weird” and my teeth feel and look better after only a few uses. I'm a heavy smoker and coffee/soda drinker. Always look out for coupons in combination with sales at the drugstore or grocery. Best time to buy.
