This is a pretty solid keyboard. You can feel its metal construction in the weight, and know that you've got a pretty robust device in hand. I won't go into the common mechanical keyboard features, because it ticks most if not all of the boxes of a device of its type - low profile, blue switches, Bluetooth.
While the hinging feels fairly robust, the keyboard could have had something to hold it securely open,, like perhaps some magnets in the fold; this would keep one half or the other flopping freely downward when the keyboard is picked up. That might be its one physical flaw as a keyboard.
While the arms of the tablet stand snap securely into place along the back edge of the keyboard, they move very freely on their own hinges while open. I'd be hard pressed to set something heavier than my phone on the stand, and only really while the keyboard is sitting flat and in place.
The only other challenge I might have is the sleep timeout value - 60 seconds when off cable and in Bluetooth mode. That counter runs out very fast, and you really don't notice until you start to type and realize that your first word is missing the first letter struck while the keyboard was waking.
Beyond that, this is a solid addition to my personal arsenal. It's replaced two other wired keyboards attached to my work and home PCs, and I've found it useful for typing longer responses to email and chat threads on my phone as well. My desk is thankful for the minor decluttering.
