One thing you will find that is nice is that Sheer White strips are longer and wider than most competing strips. Because of this, you get whiter teeth further back in your mouth and you get full coverage of the front and back of your teeth which gives a fully white effect. Often times, when there are stains on the back of your teeth that are not bleached with other strips, the stains show through your teeth as they are iridescent. 

Additionally, the, the strips use a stronger adhesive to bond to your teeth to help get a deep down whitening effect and to prevent them from slipping and sliding all over the place like other brands. It is this, that allows you to wear our strips even while you sleep!
