When I first started this venture with your company, the teeth were sturdy and they last for some time now they crack after the first week and I’m not sure if you changed how you’re making them their thinner than before. I’m not sure what’s going on, but I am not happy with the quality of work and I have expressed this before and I thought this time will be different. My first pair has already cracked and now the second remake will do the same because they’re not reinforced where I asked.
