This product is good. It’s real and noticeable. Not magical. I recommend brushing your teeth extremely well and “drying them” prior to application. Don’t overdo the time and don’t use them all the time. But yes good investment for sure.

I’ve used these off and on for 5 years. They’re my go to. They seem pricey, but you can see the effects after just one to two uses. And they stay white! Would recommend for anyone. Warning: your teeth will be sensitive

These are super easy and effective. Just remember to not drink anything for the next hour or so for best results. This is a great way to get results without breaking the bank.

These work so well. I can’t recommend them enough. I like to use them once a week. My teeth are a little sensitive, so too much use will cause my teeth to be irritated for a little while. I am so thankful I tried these!

I purchased this product and have used it multiple times since purchase. Produces sufficient results, but left my teeth super sensitive (although the Crest Sensi-strips were amazing for my sensitivity)!

Big fan of these! Just don’t overuse them or your gums/teeth can become sensitive. Definitely whitens teeth when they’re feeling dull and in need of a touch up!

Love these. Whiten my teeth tremendously and do not take long to stay in. Only downside is results are more visible after a couple times. But i think they work good.

I’ve used crest white strips since high school and they really work for me. I do a box probably once a year. They can cause some sensitivity but for me its mild and doable. Don’t spend money on more expensive treatments, these will do the trick.

I can’t even tell how much I love this. I’ve been using this for couple of years every half a year and people still are asking me where do I whiten my teeth cause they are so white !

Definitely do the job if used consistently. However I would not recommend these to people with sensitive teeth. I could not use them consecutively but had to do every other day. These allowed me to avoid the sensitive teeth feeling.
