Have been using it for a week now, exclusively at home.
Found it to be very sturdy and stable. The guitars feel secure.
There are three blocks that you can move to accommodate guitars of different sizes. Not an absolute requirement to use them, but can provide a snug fit and add to the stability. I have one electric, one acoustic, one jazz-box, and they fit with the blocks, but it's tight!
Pricy but overall looks, stability, and quality are worth it.
