Otamatone [Ninja] Shinobi Japanese Electronic Musical Instrument Synthesizer by Cube / Maywa Denki, Navy Blue with Yellow Accent Color

Very cute. I got it for my boyfriend as a Christmas present and he loves it. It sounds really good just like in all the videos online. I guess it would be nice if it was rechargeable instead of requiring new batteries whenever they run out, but the batteries last quite some time anyways.

Was hard to see at first due to the awesome camoflauge, but eventually found it and am slowly learning the secrets. Dog, cat and parent approved! Totally doesn’t annoy them at all and they LOVE for me to play it randomly! Said they have never heard such a rendition of Twinkle Twinkle and Happy Birthday before and are glad this wondrous invention was brought into their lives!

It's a great gift for creative children. Though the novelty seems to wear off after a few weeks, I see my son reaching for it every once in a while to make a creative tune. 3.5 stars.

It's smaller than the average Otamatone but it's still the same thing. I got the ninja design and it's good quality. The design doesn't fade. Batteries run out faster than expected but it could be because my friend and I messed around with it a lot lol.

Constantly died! We bought new batteries and replaced them every couple of days because it just drained the bettered so bad.It only lasted a month total before it completely died.

Gift for my son, he has lost his mind to the otamatone. He no longer speaks English only strange tech musical squeaks. It has taken over his life. 10/10 functions fine it is as described but they don’t warn you about the brainwashing addiction that follows use.

Works great, exactly what my son wanted. The only downside is that the instructions are hard to understand, but it didn't take long to figure out how to use it.

A piece of garbage! My son was so disappointed and so am I. It was smaller much smaller than advertised and only worked for two days. Will never ever but this again. And I suggest you don't waste your hard earned cash.
