Really work well - easy to use
My wife usually uses Colgate whitening strips to whiten her teeth.  She said she feels like these work a little better.  The pack comes with 28 strips - enough to do 14 treatments, and also has 8 extra strips as a free bonus.  She also said the watermelon flavor is good - not overwhelming, just pleasant.  They are very easy to use, just peel off the backing and put them on your teeth.  Then wait for 30 minutes and take them off.  She says she can see the difference after just one use.  I think these are a good value for the price.
