I bought them (not from amazon, but they're the same product, and yes I'm certain they aren't counterfeit), and they arrived fine, and were a lot of fun. Sadly, the very same day one of the ear motors broke - the left ear started making horrible clacking noises and refused to work properly. Shame.
I'm not saying that you WILL have the same experience, but do know that there is a chance. After some googling, I discovered that I'm not the only one with this problem.

So if you're not well-off and plan to save up money especially for this, do know that the possibility of them breaking without you doing much exists and maybe reconsider your purchase and wait a couple of years for neurowear to release an updated version to spare yourself sour feelings. And if you do buy them, be VERY careful with them and make sure to read the little leaflet with warnings BEFORE turning them on.

Besides fragility there are a couple of other things that may possibly bug you:
- The battery box doesn't have a counterweight, so they tend to shift to the left side of your head a little. Not a lot, just a little.
- It's made for small heads, so it may not fit you well if you are a tall person or just have a large head.
- If you don't want the headset to be very noticable, you'll need to have thick, voluminous hair and bangs, though even if you have all that, there's not much that can be done to conceal the battery box.
- Taking them outdoors is okay only if you live in a room-temperature area without excessive humidity.

Lastly, know that it isn't some kind of a miraculous future device and it won't read your emotions with bulletproof accuracy. It's a fun toy and you should treat it as such, else you will be disappointed.

If your necomimi do break, though, don't be shy and make sure to contact neurowear about it. Their customer service is very supportive and if possible they will send you a replacement in a timely fashion.

I've done extensive testing (if you can call it that) of these ears. I've had them for a few months and I've worn them to: work, parties, conventions, nightclubs, and amusement parks, plus allowed curious friends to try them on. I love my $100 kitty ears, but they are not without their flaws.

They are adorable, and they work as advertised. The ears are interchangeable and customizable, and you can buy additional ear sets from various sellers off the internet if you don't want to make your own. (I have white cat, black cat, and fox ears. Expect to spend on average about $20 per new ear set if you don't make your own).

The headband part of the Necomimi unit is really small. I am a smaller adult who wears child sized hats and I can barely fit these on my head, so people with larger heads won't be able to wear these without discomfort. Also, the black headband will clearly show up on anyone who doesn't have black or dark brown hair. Bald men, short haired people, people with light hair color, the headband and battery pack will stick out like a sore thumb. (A big improvement would be for the headband parts to come in different, lighter colors so they would blend more easily into the user's hair.). You can't wear earrings while using this either, because the ear clip sensor will not be able to fit over them. The forehead sensor is attached to a bendable bar that takes a bit of adjusting to get it comfortably touch your forehead. The unit is also a bit heavy, so the weight gives some people headaches. When the ears move you will hear a little bit of noise from the motors in the unit.

They are extremely delicate. You can't take them outside and expose them to excessive heat (like the hot summer sun) or get them wet.

I have purchased these ears for my wife to wear at work (we own a game store). At first, they worked well (went through batteries fast, but that was ok) and our customers loved them. We then contacted Nicomimi to stock them and began working that process.

Shortly after that, one ear failed (about 4 days of use, motor stopped working). I figured this was the perfect opportunity to see how well their RMA process worked. The customer service was quick, personable, and effective. I had to pay shipping, which seemed fair for an uncommon issue... but this seems to be a frequent problem. I shipped out the ears, and shortly after I received a replacement; all things were in good order.

5 Days after receiving the second pair the same ear failed. This time the motor failed slowly, but the end result was the same. Because of this we will not be stocking the ears nor will we promote the product as we do not was association with a defective product line. I am currently attempting to receive a refund, and I will report on Amazon how that process goes. We were both very upset at this situation because the ears are a lot of fun, and I think the idea behind them is amazing/brilliant. It just seems that Nicomimi went with an inferior manufacturer and their product is suffering for it.

Sounds like some people are having good experiences with the ears; so I may have just been unlucky, but there have been other reviews with the same problem. We were careful (especially with the second set) not to manually move the ears or abuse them in any way.
