Slim Fit, Solid Protection
I’ll admit, this guard isn’t as comfortable as the gel or silicone alternatives, but it does its job well. It just takes a little time to get used to that firmer plastic feel inside your mouth. After a few months of basketball wear, you can clearly see where my grinding happens and how the material has worn slightly—but it’s held up better than expected, especially across the front where I tend to catch the occasional elbow. Overall, it’s a solid pick if you want something slim, simple, and low-profile that still provides decent protection. And it comes in every color imaginable—for anyone who likes, or whose 3-ball game depends on, a clean pop of Neon Flash or Athletic Orange! — Curated by Jaded John | #OrderlyCleanDesign

Best lacrosse mouthguard
Easy to mold, very durable- has lasted my entire lacrosse season and will most likely last another lacrosse season. I know these cost a little more than regular mouth guards but they are thin making it easy to talk with him and they fit perfect. The value is unbeatable! My coach didn’t even think I had a mouthguard in oh and they stay in and don’t fall out!

Purdy good
A little tricky to get the guard to fold correctly. Had to remold several times. Not a great fit for me, but the plastic is nice and thin.

Would definitely recommend
Super comfortable and easy to mold. It is easy to drink while wearing it, and compared to most mouth guards, it’s easier to talk through.

Great Budget Mouthpiece
Easy to mold and protects very well! The size is pretty standard and fit fine, I have a larger jaw size and no issues. The material is in between soft and stiff but holds its shape.

Works great for BJJ
I use these for BJJ. I have taken a lot of hits to the mouth, no damage. Make sure you buy the right size. Breathing is easy, talking is easy, drinking water is easy. I put it in and forget about it.

nope, like x-mas wrapping an awkward shaped present
As a person formerly in the dental field, this product is certainly not worth 20 bucks at all. The shaping is cumbersome so I had to use my former life's skills to "round" out the curves that stick out to make it more comfy. After 4 tries, I got it to an acceptable form which is still a little loose but overall the arch shape is there. If you had a mold of the arch - then at least you have an easier time to reheat and cool but while on the model - winging it in the mouth is frustrating. Use boiled water in a bowl and about 30 secs is just about the perfect balance between softening and handling. Best you can do is first mold the basic shape. Once set, keep the child biting down and look at how much you have to work to round out at the curve and then curl the back up to cover 1/3 of the cheek-side crown of the teeth. That's what will be the 2nd, 3rd and likely 4th to add finishing touches. Trying to isolate and dip the sections you want to "perfect". Maybe it's me trying to get office quality mold but if you're not good with this stuff, then look for a pre arched one and not this flat one. I only got this because it was "recommended" by the coach but from my view - not good. Best option but most expensive is the dentist, but replacing broken teeth is much much more so weigh the options. I gave it a shot, this is my review for what it's worth....
