Agree it is great. We have the U11 and iPhone 8 Plus, and I don't even remember the last time I picked the 8 Plus up. One of my best friends is an Apple girl, and her iPhone 10 can't keep up with the U11 either. Oh, and USonic just blows passive headphones out of the water.
Yes, they have fallen behind in the security updates. I don't think it's been abandoned, but I should not be on the June update.
PS: Too bad the sale is only for the black version. My wife was interested in the silver.
