Has anyone tried the Dr Dent purple teeth whitening strips?

I’m not usually one for fall for a viral trend but these do look really good. Has anyone tried them and did they give good results?

Yes I’ve tried them. They sort of work in that there is a slight brightening but it only lasts a few hours. I don’t have particularly stained/discoloured teeth so I tend to use them before an event or a night out
