I read other reviewers who mentioned theirs did not contain an LED light and thought they had just got one that slipped through quality checks. But no, mine doesn't have an LED light either. Also, there was no information on where this product was made. Based on the instruction booklet, written in broken English, it's probably made in China and contains who-knows-what. I'm returning this, but would be hesitant to use it anyway - who wants to put mysterious chemicals likely from China in their body? Not me.Overall its a good product. Mine came without the LED though which is what other people are saying as well.i have been using it for about 3 weeks, it has made some improvement not spectacular but some progress..will need more time to fully have a better opinion.No LED light...take it out of our description if your not going to provide this. Buyer beware, many customers have complained about this. The kit comes with the mouth gels and tray, 2 whitening syringes, and 2 remineralization syringes. Mine came in a bag, no box.DO NOT BUY THESE! THEY WILL DESTROY YOUR ENAMEL! I tried this once and my teeth hurt so bad, I could not stand the pain. My teeth aren't usually sensitive, either. There is no way this product is safe. Stay away! Seller did not do anything to help, either!Mine came without the LED light. I will be returning .The syringes are easy to use, not messy- the trays formed well, aren't too thick so they are more comfortable than what I had previously. I've been using the product for a week with good results. The blue gel has kept the sensitivity down to nearly none.I was missing the led light .
