I bought it at our University Bookstore just for fun. Hey! I had extra money and these look really cute, so I made myself a favor and bought Koko! Honestly, at first, I did not know how to use them properly. I plugged it in my computer and it didn’t work. Later on, as I start using them more and more, I got the hang of it. Turn the volume of in case it didn’t work the first time you use it. And make sure you charge it long enough! I’ve been enjoying Koko so far! Its a great product!
