Just hold it in your hand and you’ll know - The 30th anniversary theme is special, seeing different generations of Mametchi every day is fun. This is my first nano and I like that it’s very low maintenance, rechargeable, overall a great little device. It’s really, really cute and colorful, just like the name suggested. I wish Best Buy carries the yellow version as well.
