I think I've tried them all at one time or another. Crest strips are the best low cost whitener but if you can spend the money, GoSmile is worth it. Still much less than at the dentists and works really well. Make sure you follow the directions completely to get the best results with any product you choose. Most people who don't have good results didn't do exactly what were in the instructions.

Also remember that these whiteners are for yellowish stains due to age, food, coffee, wine, and cigarette stains. They don't work on the grayish discolorations. GoSmile whitened my teeth by about 5 shades and so fast. I think it's worth the extra money.

Also, you need to order the cups that the gel go in. It's pretty much useless with the gel alone. It's very powerful and will burn your tissues for one but you need it to hold the gel against the teeth. You don't necessarily need the custom ones but they are very nice to have. If you have one that is pliable, make sure you heat it in hot water first so it will form to your teeth. Some are harder plastic and don't form as well therefore, they don't allow the gel to adhere well.

Crest strips will whiten but will take longer and won't give you as much whitening as GoSmile. I thought Rembrandt was okay but not as good as Crest and certainly not as good as GoSmile.
