- ARK Krypto-Bite, Chew Necklaces for Sensory Kids and Adults, Oral Fidget for Autism, ADHD, SPD, Anxiety, Medical-Grade Sensory Chew Necklace, XXT, Very Firm, Lavender

I got this ARK Krypto-Bite XXT Chew Necklace for my cousin's son, and it's been fantastic! The lavender color is beautiful, and the necklace is just as tough as advertised—definitely "extra extra tough." It holds up well to chewing, and he can wear it throughout the day without worrying about it breaking or getting damaged. It's soft on the teeth, providing a satisfying chew without being too hard on his jaw. Plus, the design is stylish enough to wear every day, making it a great sensory tool that looks good too. If you need something durable, functional, and comfortable for chewing, this is a great option!

I definitely needed this perfect size and shape chewing on it has done a world of good for managing my anxiety and helps with my ADHD as well. I've had others that look the same but I completely chewed through them multiple times in 1 month this ones durability is great I've had it for several months and not even a split in the pendant

Really great, well made chewlery. My daughter has autism and is a huge sensory seeker. She put dents in this one the first day but it has stood up to the test of time and she has not been able to chew through it. It is completely intact. She wants to try the softer one because it's pink. No way, she'd chew it in half before the day was out. I put off getting this for my daughter for years because I thought the idea was disgusting. Something she's mouthed, hanging around her neck. But then she went totally offline sensory wise and I had to do something. I re-examined the whole gross factor. Everywhere kids go they stick their fingers up their nose, drool, mouth, cough, sneeze, and other more disgusting things. You can't get rid of the germs. Kids aren't clean. They are petri dishes of germs. So yes, there is a gross factor but is it increasing the already germiness of your kids, the uncomfortable, uncontrollable fact is: probably not.

Very sturdy! Do recommend :)

Very satisfying to chew. As a grown man, I find that it holds up pretty well, although I'd imagine if I tried my hardest I could bite through it. It's phenomenal for rhythmic chewing, especially back in the molars. It is a bit smaller than I imagined, and I'd appreciate if they offered a tougher version than the XXT. Most of my chewing is stim-based, but sometimes, when I'm attempting to let out frustration, I have to hold myself back.

It's great and the XXT was perfect for my chewer! I wish I had thought of getting her one sooner - as I've had similar items for my son at an earlier age due to medical/sensory issues. Lately her chewing had spiked (anxiety) and this is perfect for her to wear and mouth especially with school starting (no more straws, bottle caps, bracelets, headphone wires, PENCILS, pens etc) this is GREAT! Love the color options and various styles. She chose the "gem" style and it's long enough where attention is not drawn to it so she doesn't feel uncomfortable wearing it. From the time she wakes up until the time she falls asleep she's chewing on this - and even cleans/washes it herself (that's how much she loves it)! If you have a child with sensory issues (whether from anxiety, autism spectrum, or a myriad of other) that is a chewer just see what or how hard they chew and order appropriately. Great item!

Highly recommend. It’s very durable and tough. It’s my first chew necklace and it’s a little bit too tough for my taste, I’d like something a little softer, but it certainly helps the need to chew. It’s very discreet and it’s easy to chew under a mask (wore it on an airplane for anxiety).

My autistic kid likes to bite on these. They've been highly recommended to us by both her dentist, as well as other parents of autistic children. When the kiddo started with these, I bought softer ones. I soon realized weneedes stronger ones. Now we are all the way to the super strong ones. They are no longer lasting as long as they used to. The purple one lasted only 3 days. Kiddo was using these at school and quite extensively. The blue one lasted a few weeks but with more infrequent use. I'm starting to be frustrated as they are not cheap and they are not lasting. And it's either thr chewies as we call them, or biting nails. Kiddo stopped biting nails when we started to by these. I don't want my child to go back to citing nails. I'll try other models and I'd they keep lasting as short as these ones did, I'm going to have to try a different brand. To summarize, if very strong amd constant chewer, they may not last you that long. I'd say avoid the ones that can be wore like a necklace. They seem to be weak where the hole for the lanyard is. And unfortunately, my kid keeps biting them there. We'll have to stick to the non-jewelry kind.

As a 35 year old, currently going through the ASD diagnosis process I find this chew great. It is one of only a few chews available that is shaped in a way that can be chewed on by the back teeth. I find it discreet and has also helped me to give up vaping

Our daughter chews everything, pens, pencils, furniture, books etc. This has given her a useful outlet for it and it looks pretty cool.

Bought to try and reduce my teeth grinding and jaw clenching and has been very effective for this, especially when used on the back teeth. Has also helped me not destroy my nightguard as quickly (which was expensive!) when chewed before bed. I also really like the colour and design! Good stress release!

Bought this for my autistic 17 year old. Lovely chew for a non aggressive biter. My son really liked this but unfortunately only lasted 3 weeks before he chewed through it.

The cord actually wore through the chew aid and my child was able to bite lumps off of it.
