I'm getting a lighter rail like this, because I haven't been able to sleep with the shapeable ones I've tried before, when I've felt like I'm suffocating in a big squeeze. After opening the package, I was very skeptical about how this mouthpiece would even stay in the mouth during the night, but it was still in place in the morning. I've been spared the headache caused by crunching every time I've remembered to put this in my mouth at night. The price-quality ratio is therefore very good. I could have given it five stars, but when used correctly (as in the pictures in the instructions), the edges of the bite plates and the plastic rail come too low and press on the gums/mucous membranes unpleasantly. However, upside down works and can be used.

I used it according to the instructions, it doesn't work, I don't recommend it

At first, I wondered if toothpaste could taste like candy. It's true. If you wash for more than 2 minutes, the taste will run out. But on the other hand, there isn't even an iota of craving left because the taste runs out. I will continue to buy for adults.

Fits its purpose and is easy to customize.

Good product. The thread didn't loosen up when used like with a thicker threader. It even felt a little too thin. I've used several different models and now I couldn't find anything but this one. Ok still.

The thread loosens immediately after use and cleaning is difficult. Thinner was better, even though it is meant for tight spaces between teeth.
