Great!

For both kids and adults, this Velociraptor mask is overall a pretty cool choice for a costume/toy/or just a cool display item. It works well with only minor flaws. One of my biggest worries on seeing it is that the face would be really visible through the large panels and while they give great visibility outwards, the face doesn't really stand out at all, even when it's an adult.

Basically how it works is you strap the mask on, rest your eyes and nose on goggles inside and put the chin strap on. When you open your mouth, the chin strap is pulled down and opens the raptor mouth. When it opens a little, it does a low growl. Slightly more open and it does the 'yip' Velociraptor noise (think Kitchen scene, original Jurassic Park). When it's open extremely wide it does a roar/scream. All of them have good volume and sound great! Make sure the chin strap is on tight enough because if not, you will not be able to open it wide enough to get the big roar.

Therein lies my two problems. One very minor. If you are an adult wearing this and you tend to carry a lot of weight around your chin (double chin) this will not fit. However, even if you're large and you don't carry a ton of weight on your chin, it will fit fine (I am large, but don't carry chin weight), just be aware if you are very jowly the chin strap might not be large enough. The mask itself fits easily on big heads and therefore is a little heavy on little heads, but they will have too much fun to complain.

My second note would be comfort. I see a lot of people saying how comfortable this mask is and to wear, yes, it's surpisingly comfortably. However, no matter how it's positioned (at least for an adult) it is quite uncomfortable to use. While the goggles are soft, thick, padded feeling plastic, when you open your mouth they are pulled down hard again your nose. You must really open/pull to activate the mask, so this can be painful, especially over time. Not sure if this is an issue only for adults, because when kids are having fun they don't worry or complain about those kinds of things.

Regardless, it's a really fun toy, so just be aware that comfort isn't top notch, as you'd probably expect from a toy mask (fun is the priority). One final thing that's really awesome is that when the mask activates the eyes move, which gives it another touch of realism. The mask itself is a lovely sculpt, lots of great details, glassy lifelike eyes and the paint is accurate to Blue's design (a lot of Blue toys are just generic Raptors). I'd recommend it for sure!
