I’ve got another contender: meet the Eppendorf
Eppendorf is a centrifuge manufacturer, you know those round things that scientists put those little tubes of liquid into and it spins really fast to separate the different components of the liquids inside the tubes?
Well they have this model that [I think] came out recently that has a special cap that goes into it. Does the cap look familiar?
So I guess someone who works for this company likes to play with yo-yos and figured out a way to turn these caps into a yo-yo. Thus, the Eppendorf was born.
They did not sell these, but instead they were offered as a free incentive to fill out a simple survey on their website. This news was dropped into the yoyo community on Instagram and I just couldn’t help myself. I went and filled out the survey, literally like 5 questions, and about a week later this little guy showed up in my mailbox. I actually thought this whole exchange was hilarious.
The yoyo came setup responsive, and I don’t have a scale but this thing is way too heavy to be a responsive yo-yo. It was kind of terrifying to play it responsive. So I threw a regular size C bearing in there, and this thing is a novelty at best. The weight distribution is all over the place, it is the heaviest yoyo I have, and those raised ridges in the catch zone are extremely frustrating because the string gets caught on them regularly during play.
It is collectively the most unique, worst, [rarest?] and terrifying yo-yos that I have in my collection.
I think this is a pretty good contender for this list
