Don't waste your time and money. I bought it even though there were a lot of negative reviews. These don't work. I've tried all the syringes but to no avail. I've been whitening my teeth for years using syringes from the dentist's office at the same percentage. Already after one procedure there are noticeable results. Not with these. FYI: The expiration date is on the outer packaging, which doesn't appear to be related to the product. Don't buy this.
