Perfect Competition Mouthpiece
Very strong, easy to shape! Perfect for my martial arts competitions. You can easily talk and breathe while it’s in. I like that it molds to your teeth for a perfect fit. Shipped timely. Highly recommend!

Well made & works well.
I have had many bite guards. Some that cost hundreds of dollars. When I first opened package I thought this one was not going to work. It is thin & comes in small package. AI was pleasantly surprised. It is easy to mold, fits securely and I don’t bite through it. I am very happy with it!

Great quality and easy to use
This is great lightweight mouth guard that was very easy to fit and mold to the mouth. It is comfortable and gives a snug fit without giving any pain or discomfort on the gums. It is nice and hard once it hardens after molding and seems like it will hold up well. It is very easy to remold if you don’t get it quite right the first time. Just follow the tutorial and molding is pain free and easy to do. This is great for kiddos who are in the teeth losing stages and need to change up mouthguards often

So far, solid mouth guard.
Recommended by LAX coach for youth lacrosse. Medium size seems to fit a petite teen (just at the bottom range of the height range for Medium Size). Seems to fit well, and the thin material allows talking, which is important. Absolutely no problem fitting it after watching the video instruction a few times. Will add the fifth star if it is as durable as some have said. Scary to think about, but a nice touch is that the company has a $50,000 dental guarantee of protection. Knock wood we’ll never need to find out if that’s legit!

Work great and as described even for little kids
These are great! I got the size small for my 6 and just turned 9 year old for wrestling. They couldn't breathe or drink with their other mouth guards and would not wear them. It took me and my 6 year old about 5 tries to get the mouth guard formed properly, but even she was able to work with me to do it. My 9 year old only took two tries. They both like them and have no problem wearing them. Also love all the colors, I was able to buy them each one in their favorite color. Since they are still losing and growing teeth, I love that we can reform these many times too! Also, water temp is important! Use a meat thermometer. The temp on the package is like 160-170 F I believe. NOT boiling. Any cooler than the 160 and it won't warm enough to form right. Just read the directions and watch SISU's YouTube video before you start.

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....

Very good. Allows you to talk as described. I use a thicker one when completing, but this is ok for sparing. I will buy another one when this tires

Compré una talla más grande pero aún así se amolda bien aunque haciéndole un leve arreglo , es cómodo aunque duro, se puede respirar y hablar.
