Good Product
I first bought this oproduct from my Dentist office. It now is sold on Amazon for a bit less cost. It is a good product, easy to use and I have had good results. I tend to forget to use it on a regular basis, but even after one or two treatments my teeth are brighter.

BEST TEETH WHITENER OUT THERE
I have tried probably like 15 different brands of teeth whitening within the past 5 years. this is BY FAR THE BEST. This is legit basically dentist grade whitening that actually works. No bs or marketing just results.

⭐️⭐️⭐️⭐️Professional-Level Whitening Without the Hassle—Just Mind the Price Tag
After trying the 15-day treatment, I’m genuinely impressed by how effective these whitening trays were. My teeth brightened by about two shades, and the convenience of doing it all from home makes this a standout option. 📦 Well-Packaged and Ready to Use: The trays come neatly packed and individually wrapped, keeping everything clean and easy to store. It’s clear a lot of thought went into the packaging—not just functional, but also a bit polished. 🧪 Powerful Whitening Formula: The whitening gel is no joke. It delivers noticeable results without causing the sensitivity I’ve experienced with other brands. Just be ready for a slightly funky taste—not exactly refreshing, but totally manageable and far from unbearable. 🏡 No Molds, No Dentist Visit Needed: The pre-filled trays mean you skip the hassle of getting custom molds or visiting the dentist. Just pop them in and go. It’s a simple, at-home solution that feels much more professional than most over-the-counter options. 🦷 Fit Matters—Bite Down Firmly: You do need to bite down with decent pressure to ensure the gel makes good contact with your teeth. If you don’t, the results won’t be as even or effective—so give it a proper bite and wear time. 💸 Pricey, But Cheaper Than a Dentist: Let’s be honest—it’s a bit expensive for a DIY remedy. But when you stack it up against the cost of an in-office whitening treatment, it's a clear win. You're saving hundreds, even if the upfront cost feels steep. 🎯 Final Verdict: If you want noticeable whitening without the dentist markup or mold drama, Opalescence Go delivers. The results speak for themselves, just be aware of the taste and budget. I’d recommend it for anyone looking to upgrade their smile at home.

They work and no sensitivity!
Easy to use and they actually work if you use them consistently. I buy them for me and my daughter and neither of us experience any sensitivity issues.

Timely delivery in great condition
This product works well. And it whitens gradually so you don't look fake, there's not such drastic difference with each treatment.

Actually works!
I was thrilled with the results I got from using this product. I’m so used to hair and skin products that don’t really deliver on their aesthetic promises. But this product actually made a visible difference and made me less self-conscious about my teeth. It caused slight sensitivity that lasted for a day after each use. I found the sensitivity wasn’t as bad as Crest white strips.

Not what I was expecting, not worth it for me.
I got these hoping they would be better than the strips I was using. I was wrong! These are terrible and I will not be rebuying. Firstly, there’s more to these than just the strips. With the strips, you peel them off, stick them on your teeth, and wait the amount of time. Easy. With these trays, you have the main plastic tray, then the weird waxy tray that holds the whitener. You have to push the main tray on and kind of suck the waxy tray onto your teeth. It always takes me several rounds to really get the waxy tray to stick and it feels like a sports teeth protecter when they are in. On top of that, the whitener inside the waxy tray is clumpy and I almost wondered if it was old/expired but the box didn’t have a date that I could find. It should be like a toothpaste and kind of squish around your teeth, but every time I take these off, there are clumps on my teeth and the stuff doesn’t seem to be spreading appropriately, which reduces the whitening effect of the product. I noticed spots on my teeth where the clump balls would be and would whiten in spots. Also, these are designed for perfectly straight teeth. Now, I don’t have crazy crooked teeth, but I do have one, on the bottom row that is not perfectly aligned. I’ve never had any issues using strips, but these trays don’t work well at all. The top row fits okay and seems to stay once you manage to get it on there. But the bottom row never fully covers that one tooth that isn’t perfectly aligned, and it slides around on my bottom row very badly and doesn’t whiten evenly. Overall, the Crest brand whitening strips whiten better, stick better, and are cheaper than these with less hassle and less overall waste.

Deformed trays
My teeth whitening trays are bent and ill - formed. I love the whitening effects, but I am unhappy that the trays are basically deformed. This makes it super hard to use. This is an expensive product, I expect them to fit my teeth.

We originally stated using this product through our dentist. His price is twice the price of Amazon..so it looks like I’ll be buying from Amazon from now on!😀 These are the best whiteners I’ve used and have used different types. Very comfortable, much better than using strips!!! No sensitivity and they work!

I saw on some YouTube videos that this product was recommended by several dentists and orthodontists. I tried it and then saw how quick and effective it worked. My gum became a little sensitive after 9 days so I spaced a few days between application and it was much better. After 6 months, the whitening effect is still there. I would like to do it again to make them even whiter.
