Since it is 90-day Woot warranty, i assume it is NOT refurbed by Apple. Which makes it much more YMMV from my experience w/ Woot refurbs, sorry to say.
I want to bite on this, but these are going from 15-25 bucks on eBay and you know exactly what condition each one is in when you bid.
I’d take a chance if this were less than 18 bucks but 27 with random condition is a no go for me.
Still, well built keyboard that lasted over 15 years and will probably last another 15 years with proper care.
