Just got two of them for my wife and I. Light weight, stand works great. A little longer than both the standard amazon pw case, and my $8.20 aliexpress knock-off. The brown Aliexpress is my favorite and looks fantastic, but I like having the functionality of a stand for reading and eating, or while in bed.
