I pre-ordered this in April for a May delivery. The Roku Xpress I’ll ordered in July 2019 ran out of space very quickly. I could not stream YouTube, and I could not stream something on Prime if I had the Netflix app up also. In other words, I had to uninstall Netflix if I wanted to watch Prime and vice versa. My new Roku device is wonderful. I can stream all three of those big channels and not run out of space.
I prepurchased and received my Roku Express 4K+ in the mail a couple of days after the launch date. It was very easy to set up and use. I have more choice of shows to watch now than when I had Dish TV with NO monthly bill.
