Bought xbox one s as "open - new". And it was "open - new" (y)
I bought the SteelSeries Arctis 1 Wireless from their clearance store - box was damaged but all the plastic wrapping had been untouched on the headphones themselves and looked like it had never been used. Guess I could've been lucky though!
I bought an open box msi laptop with codes from for nearly half price. I was concerned but It was literally open box but brand new. My only experience. At half price or 60 percent go for it but less than that I wouldnt bother.
Buy brand new Sennheiser HD 599 instead imo unless you really need a mic
In all honestly, who knows with curry's.
