To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I loved the fact that my cases looked exactly as shown in the picture when I received them, I just had one small problem. All of the cases were dirty inside as if they had already been used. YUCK! Which is why i am only giving 4 stars. It wasn't enough to warrant sending them back to the seller,so to fix the problem I just sterilized them on my own. Other than that I like everything about them.
So I read some reviews of other products that were exactly like this one. I learned that they're cheap and fall apart quickly. So I bought a multi pack in hopes that I could get at least 6 months out of them before having to replace. I guess I didn't think they'd fall apart in 2 days. So I've owned these for the last week or so and I'm already down to the last two because the "hinge" on the back of them come separated very easily rendering them completely useless. This is garbage. DO NOT BUY.
My kid can't keep up with a retainer case to save his life. He's really great with his retainer, but not the case. I thought having 5 would make it easier, but he still loses them. I'll keep buying these. We have had a couple break, but these are just prone to that, especially when kids toss them around, throw them in their backpack, etc...
