Has anyone tried this really cheap teeth whitening?

I always see this advert com up and wondered if anyone had actually tried it?

I would be very cautious about using something I'd ordered off the internet. While we lived in Bangkok I considered getting my teeth whitened. The dentist I saw was very good and advised against it , she told me it didn't suit everybody and at my advanced age (40) my teeth would already be weakened and this could cause them to be brittle. I am not sure if it's true or maybe she didn't know how to do it, whatever the reason I'm pleased I didn't. Imagine having teeth as white as those, you'd certainly show up under ultraviolet light.
