Listerin Whitening Strips

I bought the listerin whitening strips becuase I didn't like how all the other strips move all over your teeth.After trying to figure out how they went on your teeth, I got the top one on to get part of it stuck to my lip.So had to throw that one away.Tried again..it was a success.The stayed on my teeth for about 10 minutes until they disolved.But I found that they didn't disolve all the way and that they left a gummy texture on my teeth after everything else came off.They did however make my teeth really white.A lot better than some of the other whitening brands that I have tried.So all and all I think I will use the whitening strips again but take my time when putting them on.
