The answer is yes. A couple of months ago my wife went to the dentist because she was interested in bleaching. The most cost effective method available was a kit he sold her containing 2 mouth trays and several seringes of a bleach solution. He says he gave her a discount, at any rate the cost was $350. My sister who goes to some hoity-toity dentist heard of this and said we should have bought Crest White Strips but the Premium ones. Her dentist recomended them, said they work just as well at 10% of the cost. Well I found them on sale for $29.99 and bought them. You use them for 30 mins twice a day. I have 2 more days to go and my teeth look as good as my wife's $350 dollar bleach job. She's happy for me but pissed at tha fact she could have saved a ton of money. Well now we know. If you've been on the fence try them. I don't know how good the Crest Classic White Strips work but the Premium ones are awesome.
