I already trust the Hercules brand for mic stands, guitar stands, etc. so when musician friends recommended this tablet/phone holder, it was an easy decision to purchase.It's incredibly well-built, and can attach to most tubular microphone or music stands as well as square tubing or even the edge of a desk or table. There are also ways to alter it out of the box to thread onto a camera tripod mount or the threaded end of a microphone stand.I needed a mount that would allow me to mount not only my aging iPad but also my smartphone. The mount expands to fit both very easily, and the holders can even be adjusted to hold onto a larger device diagonally.All of the threaded knobs to hold the mount in place are very durable-feeling, and easily to adjust without tools.I've already used my mic-stand with this mount on a couple of music gigs, and the only thing I've been cautious about was maintaining a very sturdy balance once all of my gear is attached.Highly recommend not only this mount, but anything from the Hercules brand.
