Guess I'm the first to get one... Ha!
Got it at BestBuy with the 2 year protection plan.
I'm charging it up now. It synced right to my iPhone 8+ with no issues. Once it charges I will take it out for an activity and see how things work.
I recently got the 5x (less than a month ago), and if all goes well with the Plus, I will probably sell the 5x for like $400.00 if anyone is interested.
i will keep you posted.
