I received a new TiVo Mini VOX to replace one zapped by lightning. My original one was manufactured in fall of 2019 and has a SKU of RA9500. This new one was manufactured in February 2019 and has a SKU of RA950B. Any idea what the difference is? edit: This had a @weaknees card in it, and I was expecting new, so I'm thinking the seller (NOT weaknees) may have sold me a refurbished unit without advertising it as such.
