A decent stand, although not super stable. Meaning, I don't think a heavy laptop will be supported well. A 13" or 14" laptop will not be an issue, its the 15" - 17" laptops that are gonna be questionable. I bought as I needed something for my tablet, which has mostly worked well.
The ladder for elevation is limited, but I doubt they coulda added another notch to bring it up higher, as stability would probably become an issue.
Another issue I discovered with using a tablet, is you can't plug the powercord in if using the tablet in portrait mode. Not an issue if using in landscape mode.
Last issue was the included cell phone tray. I found it problematic with even a thin protection cover on my phone. The plastic flanges are designed to be used with a phone and no cover on it. Imagine you could use a razor knife to cut the plastic flanges some, but the flanges sit close to the phone screen, so not so sure I wanna take a chance it'd scratch the screen.
Overall, I think it's a good stand, but with limitations depending on your intended use.
