Where is this manufactured?

This is a Proctor and Gamble product. The corporate office for P&G is US based, located in Cincinnati, OH. But I do not know where the specific factories are located.

Is this an original crest product? i can't seem to find the same "levels 34 whiter" on the crest website and anywhere else, except for amazon.

This a crest product, probably just an older marketing gimmick.

Does your light stay on for 5 minutes? Mine only stays on for 2 minutes then only seconds if I try to turn it on again.

Yes, mine stays on for 5 minutes.

At the top of this page it say the product "uses the same whitening ingredient dentists use". What type of peroxide is it, & in what concentration?

I have no idea, but I can tell you these strips really work!
