I don't think this product is always worth the money. The whitening effect hasn't been great and isn't particularly long lasting. For the price and sensitivity it causes, I expect more

Really whitened my teeth short term but it really made my gums sensitive and a couple months later my teeth returned to their previous color. Definitely have to keep using it every other month to keep the whiteness

Are use these for my wedding and it seem like they did a very good job at removing stains since I am a big coffee drinker but probably only change my teeth shades by one or two she differences but you definitely notice a difference.

These work in whitening teeth for a short to moderate term effect (have to keep using to keep it up). They're drugstore but still somewhat pricey. They make my teeth too sensitive to keep using with any regularity.

These actually really hurt my teeth but I think that they did help make my teeth whiter. I don't like how they have to stay on for so long but if they work I will do anything to make my teeth more white

Pricey but this works. Made my teeth sensitive though I followed the instructions. Exploring my options to whiten my teeth at home. Taste is doable. Not too sticky.

These are so great! I saw a difference in teeth coloring after 1 use! Easy to administer compared to other similar products, not a lot of residue left behind.

When I want to keep my teeth white I use the whitening strips one time a week usually on Fridays. I keep them on from 30 minutes to an hour depending on the package. But there is always a result of white Teeth when the process is done

I've used these strips my whole life and never disappoint! I always get compliments on how white my teeth are and I've recommended these strips to all my friends and they have said that their teeth have been turned white

I like these. They make my teeth really white but I don't keep them on for long because they can and WILL ruin your enamel and make your teeth sensitive which is something you don't want.
