    Great device for sensitive teeth

    This is an easy, enjoyable way to whiten teeth. It’s super convenient due to your phone or any device being the power source. I can hook it up and do other things around the home or go on my merry way. I’ve done it in my car on my way to drop off my kids, haha. It comes with three whitening pens, which can last a good amount of time if used properly. You can see a difference in just a few days. My teeth aren’t terribly stained but I have one stubborn tooth, and I drink tea everyday. My goal wasn’t to be the whitest or brightest but to see a good realistic difference in my teeth. Which I did. I tried to use this for 30 mins a session. Especially on days that I knew I would be super busy and wouldn’t have an opportunity to get to do a second full treatment at some point within the day. If I didn’t have 30 mins which I believe is the max treatment time, I would get in a 15 min treatment and then do 30 mins that evening and vice versa. FYI you don’t have to do full 30 mins or even 15 mins. The time can be less, that’s what I chose to do but you can tailor your use to your schedule. So NO you don’t need to be still for 30 mins. I was able to use this for 21 days and it was such a good experience I will continue to use this device and their whitening products. I have not experienced any sensitivity issues whatsoever, which is great because not all sensitivity products are made equal. I went from a 4 to a 2 on all but one. My stubborn tooth went from a 5 to a 4. That one has always been a difficult one so I didn’t expect much from it. The only issue, which isn’t a big deal is I wish that it came with a small travel bag or pouch that would hold the teeth color guide, device, and pen. I currently use the box that it came in and after time it will not hold up to damp environments and constant use. It does come with a guard/cover that fits over the mouthpiece. There’s also nothing to keep the long cord manageable.

    My teeth did not whiten

    I had never heard of Snow brand before trying out their teeth whitening kit, so I asked my dental hygienist about it. She's a bit of expert on all things 'teeth whitening' but she said she had never heard of it either. The reviews on Snow's website were all positive, though, so I was very excited to get started and having pearly white teeth again. Btw, Snow's whitening kit is hardly my first attempt in getting my teeth whiten. I've tried various methods in the past but the only thing that really worked was a $500 treatment at a dentist office many years ago. However, the results were short-lived because I never gave up consuming teeth-staining food or drinks after the treatment as my dentist recommended. To this day, I still consume teeth-staining food and drinks, so I was glad when I didn't see anywhere on the instruction or Snow's website telling me I couldn't have them while using their kit (it does recommend no food or drink after each treatment for about a hour). I experienced a couple of snags even before start using the kit, though. Upon receipt of the product, I immediately noticed that the exterior plastic wrap was partially torn. I was concerned for the safety of its content but a rep from Snow assured me it was safe to use. I was relieved to see the interior box that housed the mouthpiece had another layer of plastic wrap, so I knew that the safety was not compromised. I was excited to begin my treatment but I hit a second snag. I couldn't open the mouthpiece's plastic container. I struggled for a while and almost had to tore it open before it finally opened. I never closed the container because I knew it'd be a struggle to get it opened again. Snow's engineering team needs to come up with a better design, so it would open and close more easily. Another thing worth mentioning is that the enclosed manual was a bit misleading when it tells you to 'apply lip balm' before beginning your treatment. The image of the lip balm is a Snow brand product, so I thought that was also included in the kit - it is not. I do recommend applying generous amount of lip balm (of your own) beforehand as your lips get dry and chapped. The last thing to note is that if you plug the mouthpiece to your iPhone and have your screen on auto-lock, be sure to disable it. Otherwise, the blue light shuts off when your phone auto-locks in the middle of your treatment. So, I completed my 21-day (9 min. treatment each) challenge but unfortunately my teeth didn't whiten and remained between 2 to 3 on the enclosed Shade Guide. The results likely vary for each individual but based on my personal experience, I wouldn't recommend Snow Teeth Whitening Kit.

    The Snow Diamond Teeth Whitening Kit is a nice and complete home teeth whitening kit. Packing is nice, it comes with a whitening LED mouth piece that has connections for whichever phone or electronic device you have to connect to enable the LED lights on the mouth piece. It also comes with three whitening sensitive teeth gel whitening wands. Just to preface, my teeth are stained by high amounts of tetracyline anti-biotics from when I was a child. It is an intrinsic staining, which means it's part of the tooth enamel. Just to be fair about the results. I started the 21 day challenge at 7 on the whitening chart, after all is said and done, I ended up around a 4 or 5. So it does work, but I knew the results wouldn't be as dramatic for me. My teeth were not sensitive to the whitening gel, but it does tingle your gum line initially. They also state lip balm keeps your lips fresh, but it actually keeps the gel from irritating your lips :) The LED whitening mouthpiece comes inside a protective case. You need to remove it from the clear case. On day one, I had the whole case in my mouth. I figured out how to remove the mouthpiece on day two :) Doing the 21 day challenge forces you to remember to brush every night, and to be honest, my teeth feel cleaner and smooth like porcelain. I think it will be effective for normal stains and possibly get others to a "snow" white teeth if their teeth just needs a little boost in whitening

    This is the first time I have ever used a whitening kit for my teeth, and overall, I would say it did have a positive change in making my teeth whiter. That said, I did not suffet from stains or yellow teeth prior to using the product, and so the before and after images might not reflect a big change in color. Overall here is a breakdown of my review: 5/5 Unboxing – I care about the experience when opening an item, and this one showed that there was time taking in consideration for the buyer. 4/5 Kit Items – the kit states that it will provide 75 at-home uses, however, with little to no instructions, it’s hard to determine how much of the whitening gel to use, and so I ended up using a lot at the beginning simply because the manual or the box had no detailed instructions. 3/5 Application- I appreciate having a shade guide, but the user manual could really use some work or at least a link or QR code to a video that shows how to apply the product at home. I was not able to use the kit for 75 uses. Overall, although it was hard to learn how to apply the whitening product, I would say I am very content with the results.

    This is the best kit I have tried yet, however my teeth still have not reached my “goal whitening level”. I definitely saw a slight improvement in my whitening level, but it is not as drastic as I expected, based on the reviews I read. (My teeth were not extremely stained, but they definitely did not pass the “tissue test”.) I did notice that my teeth are slightly whiter for about 6-8 hours after a 30 minute treatment, but it does fade. I am going to continue my “once a day 30 minute treatment” until I can comfortably get to a sufficient whitening level (hopefully I can pass the tissue test). My favorite thing about this whitening kit is the “no sensitivity” afterwards. Literally no sensitivity, which is heaven sent. There is also extremely minimal “chemical” taste, which made 30 minute treatments much more pleasant. Overall, it is a great whitening kit, just wish it was a tad stronger to whiten my teeth more.

    Easy to use. My teeth are super sensitive so this is a win for me as they don’t hurt after using almost every day for three weeks.

    Really nice whitening kit. Great value for the price comparatively and it works well. Normally I have to be careful because there can be issues with teeth sensitivity for whitening sets but I never experienced that with this one and it worked well.

    Snow diamond at-home teeth whitening kit had me so excited. I've used it for just over 2 1/2 Weeks. It's well-packaged and constructed nicely. And other than having an overly aggressive peroxide scent. I followed instructions correctly using the Snow Diamond at-home teeth whitening kit. But my results were far from what I expected. It comes with everything you need for a brilliant white smile but does not deliver. But it needs results. You get a peroxide cleaning solution that will be recognizable by smell. The Ultraviolet cleaning tray and great instructions were easy to follow and get you on your way. I noticed nothing different in the color of my teeth. I used it daily for about 10 to 12 minutes, and I was excited and hopeful that I would see snow-white teeth. It had a pretty light show, and I got excited. But after daily use and sitting in one spot, teeth gripping the whitening tray, I got nothing near mediocre results. I'm just one person, but maybe I followed the steps correctly, but I feel it was a waste of my time. It didn't work for me, but perhaps it'll do it for you.

    I love it- I’ve used it almost everyday since I got it and I’m seeing results so fast. My teeth aren’t sensitive, so I go for the full 30! So much better than the whitening strips I used to use. Definitely put chapstick on before you use though, makes it much more comfy:)

    Purchased for christmas for my wife. She used it once for ten minutes just to be careful the first time on her gums. It made a difference the first time noticeably. Good product. Also a lot of the serum comes with the kit. Like a whole years worth.

    It is a great product if you use it frequently because after the 28 day challenge your teeth return to their original color. That means you will have to purchase this product over and over. I would recommend it if you want to show off a white smile for a special occasion.
