After a month or so, I can see a difference . Not cheap but it works way better than white strips, and they are not inexpensive either. I use the gold serum for 30 minutes each day. My mouthpiece stopped working, only a third of the lights worked, I called SNOW and they sent out a replacement immediately. So I'm satisfied, it does what it says.
