This switcher is really built to last. The frame is solid and the switches move into place properly (not flimsy in any way). I am a bass player and singer, so I use it to switch my vocal mic from going into my TC Helicon VoiceLive 2 Extreme, and my Boss VO-1 Vocoder. It's just great to be able to use one mic for both purposes.
Pros: Very sturdy and well built. Serves its purpose perfectly.
Cons: Doesn't have a power supply plug so you have to use a battery. I would recommend using rechargeable batteries if you're a working musician because the battery won't last too long.
