[This review was collected as part of a promotion.] I got the Crest WHT EMUL Light 18g/21mL 3ct a while ago and had high expectations. I have used it enough to know that is not a great whitening product. Everything is straight forward and the instructions are pretty clear but the applicator is only effective on the front teeth it is not really useful for harder to reach teeth. The results are okay.

[This review was collected as part of a promotion.] Crest has a ok product. I got this a month ago and I really haven’t noticed any change to the whiteness of my teeth. I’ve always been a Colgate user but thought I’d give it a try. I’ve gone back to Colgate and that’s where I’ll stay

[This review was collected as part of a promotion.] I was truly surprised on how quick I seen a difference when using Crest Whitening Emulsions with LED Accelerator Light! Just using 3 days wow what a brighter and whiter smile I have!! So easy to use and no need to brush or wash mouth afterwards and also safe to use everyday!! The LED light has a little spatula on one end so no mess on your hands I'm really surprised with this product and definitely recommend to all!!

[This review was collected as part of a promotion.] I love how easy this is to use. The paste spreads easily and stays on the teeth for 30 minutes. The LED light fits comfortably in the mouth. I’ve only been using a few days and it seems my teeth are getting whiter. I’m impressed.

[This review was collected as part of a promotion.] I have tried several different types of teeth whiteners but have never had much luck. They either didn't work, made my mouth sore or they were messy. This works great with noticeable results almost immediately! I didnt noticeable any problems with sensitivity and it isnt messy at all.

[This review was collected as part of a promotion.] I've been really impressed with my results so far! I've been doing this for a few weeks now, and didn't things would be progressing this quickly! Having said that, the kit is super simple to use - just paint onto your teeth and use the LED lights for extra power. It's really that simple! I used to use the crest whitening strips every year or two, but with those I was always a bit worried they weren't making 100% contact with my teeth. Now, I worry no more! Highly recommend!

[This review was collected as part of a promotion.] My opinion regarding this product may be biased as I have had professional dental whitenening done in the past. I, also, have impressions that I can apply professional dental quality whitening product to my teeth. This product falls off quickly if your teeth are not dry. The directions to say to apply to dry teeth in their defense. The light is eh. I really don’t see the product offering any whitening. My teeth looked the same after several uses. I did feel it starting to make my teeth sensitive so I backed off a bit. My overall conclusion is that this product may be good for maintainence, but not for whitenening properties.

[This review was collected as part of a promotion.] Crest has a reputation for high quality products, and this is no exception. The packaging is really attractive and the product itself works great. Slight sensitivity which is to be expected. I'd buy again!

[This review was collected as part of a promotion.] Got this to combine with the 3d whitening past and after 2 uses my teeth seem to be maybe half a shade whiter, its hard to tell this early but it reminds me of the expensive old whitening treatments the dentist does for hundreds of dollars. My last dentist called it zoom whitening. This seems to be just as effective for a fraction of the price. 10 out of 10. Do recomend.

[This review was collected as part of a promotion.] I received the Crest Whitening Emulsions with LED Accelerator Light Kit. The kit includes 1 tube 0.63oz leave on treatment, 1 led light, 1 whitening wand and 1 stand. The stand is little under 3 1/2 by almost 2". The stand holds the leave on treatment and wand. The wand has a tight fit in stand. However the treatment fits in stand but it is loose. I wish the stand had a place for the led light accelerator or a container but there is nothing. The wand is about 5 1/2 inches long. The wand is very lightweight and the body is plastic. On the top of wand where you apply the product to your teeth is a soft rubbery tip. The wand does have some grooves in the tip but it is very easy to clean. The treatment cap is very easy to open and the product comes out very easily. The treatment is sort if clear in color, but when applying it looks white on your teeth. But the product dissappears after wating for up to 30 minutes. The treatment for me sort of had a tingling feeling but nothing extreme. The tingling was nothing more than using regular toothpaste for me.  Once you apply the treatment to your teeth you should wait for up to 30 minutes before placing the led accelerator light in your mouth.  They recommend not eating or drinking during this time. To me I felt the time to wait was a bit to long.  But the product is not runny and has a good taste so 30 minutes went by fast for me.  The led light has two buttons on each side that need to be pressed to make light work. You can easily press buttons again to turn the led unit off. The buttons are easy to press and the led unit is not heavy. It is very easy to hold in your mouth. The led light goes for in-between 3-4  minutes before it shuts off.  The cleanup of the led light is very easy. There is really no area for the product to get stuck and the whole light unit is inclosed. I really like you don't need to clean your teeth after using this kit. The treatment just disappears on your teeth. But I did rinse my mouth with water after to make sure nothing was left. The instructions state you can use this up to 4 times a day. I feel this whitening kit would be good for many people to use every day.
