I have been using these whitening strips for many years. When 3D Whitening Strips came out I tried them and then went back to these. The original ones were flexible/thin and I was able to position them so they would whiten my upper teeth as well. In addition, I have found that their whitening efficiency is higher than that of rigid 3D models. Fast forward to September 2020 - my last repeat order: the product I received is no longer the original: it's hard, thick, different shape. The shape of the lower band definitely doesn't suit me. As for the top, I can no longer position it to whiten the top teeth - either put a perineal strip on the gums or leave the top teeth. I know some customers prefer 3D, which seems identical now, but I and I'm sure others were faithful to the original for good reasons. I'm disappointed and annoyed - I would return them but it's really not the seller's fault. If CREST wants to consolidate their manufacturing processes and only produce rigid 3D prints, why not just be honest and stop releasing the product? I find the use of the same packaging and the same name misleading advertising.
