The process was stressful, trying to get the molds perfected and then sending off and waiting for the final product to arrive. I had to order extra putty to get the moulds right. It felt like forever! And then the product arrived and looked completely different to what i expected. It made my teeth stick out more and still uneven. If i already had straight teeth then i wouldnt have bothered with the product in the first place. I expected this to give me a nicer, straighter looking smile.
