Product is a great choice as it is minimal so it does not make it hard to breath when playing. I also like the authentic fit and being able to mold and re-mold as much as necessary to get the proper fitting.

i saw a lot of bad reviews that kinda scared me about it being hard to mold, or melting/shrinking when trying to mold. I followed the directions on the packaging and in one go I got a perfect mouthguard. Locks in nicely against the roof of my mouth, I can talk, drink water, whatever. Very comfy!

These are our go to for sport mouth guards. They are much thinner than others which makes them more comfortable. If your kiddo likes to chew on the mouth guard, my daughter states that little flecks of plastic don't come off, like her other brand was doing.

Molding is a little time consuming since we had to do it a few times to get it even. Haven’t used yet, but seems okay!

Easy to fit and use. Can definitely breathe better wearing it.

The design is perfect for my 13 yr old daughter that wrestles. She is able to breathe, talk and drink with it in and does not choke on it like other mouth guards she has tried. After a mouth injury where she had to wear a retainer (Invisalign type) full time for a few weeks to stabilize her tooth she was able to reshape the mouth guard over it. We will be back to purchase more for our other kids that are in sports.

I got this for my son for wrestling after he chipped a tooth last year and the dentist suggested I buy a mouth guard at a store or offline for him as it was a lot cheaper than one through them. He has used this mouth guard all season he can breathe, talk & wrestle with it in. He says it fits so nice and snug to his teeth and has held up great but he did tell me he wants me to stock up so I'll be buying more as he's thinking about using it for football season too lol

The most common mouthguard for roller derby. The Aero was the closest size for me. Forming and fitting it was a learning curve that took me about 8 tries. Here’s what I’d recommend:Hot but not boiling water. Sisu advises boiling water will ruin the protection. I used water from a coffee percolator. That didn’t seem to be hot enough to get it soft. I brought water to very close to boiling, let it cool for a minute, then poured it into a Pyrex measuring cup.Use a mirror. First position it so your front teeth are on the bite pad. Gently close your jaw and push the sides of your cheeks to push the sides up. At the same time, use suction but not too much!! The first few times, this mouthguard was painful when putting it in after molding. I think this was because I used too much suction. Just gently hold your jaw closed and use light suction.Hold it in place for 5 minutes or so so it doesn’t change shape. If there are pointed ridges on the outside lip guard from bending, dip those creases back in hot water for a few seconds, put the mouthguard back in and smooth those creases out.Finally, the last try using less suction and remolding the creases out made this comfortable with no pain when it cools down!

Waaaay better than any other mouth guard we’ve tried.

Got for my 9yr old son and we tried numerous times but couldn’t mould the dang thing. Waste of money for us :(
