The microphones themselves aren't bad. The box is a bit crumpled, but you can use it. All microphones are good to 0.0001 when both ends are tested to standards. If you work full-time in a machine shop and need to use microphones all day, every day, look elsewhere. Part-time/hobby/low-use users, this is a great alternative to a high-end set that can cost anywhere from $750 to $1,500 or more.
