Not sure it's the real deal
I think you get what you pay for and in this case these were the least expensive on Amazon. Sure the expiration date on the back says they haven't expired but I've used all of the applications and none of them seemed to be effective. I didn't get that bubbly feeling when wearing the trays nor did I get any sensitivity to my teeth like I usually would if fresh product. I wouldn't buy this again from this buyer because I really feel it's probably old stuff.
