What is so great about Buzz-on yoyos
What isn’t so great about Buzz-On yoyos? 
I mean why are they always out of stock and everybody wants them
They’re always out of stock because they aren’t made anymore, pretty much. And I don’t really see a massive need for them.
They’re really awesome for 3a. The plastic body with embedded metal rings makes for long spinning yoyos that won’t hurt each other too much when they come in contact.
