sorry, I missed this post earlier, if you look at the back of the box where the barcode at the bottom right is you'll see the part number is shown as SGGCX2PRO+ there may be a sticker over the factory barcode if they've added separate bar codes for Amazon (not sure what else is added locally there)
I think they added those stickers in the USA to avoid support calls from people thinking they got the wrong version, the stock has all been PRO+ for well over a year now
