    Had one channel defective on my first one, but was swapped with no quibble at all. Great service.
    This drives a variety of phones well (including Studiospares own 1000s!) including earbuds, with plenty of clean volume available, more than most of my cheaper phones can handle.
    The mono switch is useful too, especially for rehearsing along with some tracks with confusing stereo mixes, and checking for phase problems.
    I've not noticed and issues with noise pickup from the power supply, with 6 mics on a drum kit in my VERY compact room (9'x9')
    Only minor suggestion would be the markers on the controls could be more visible, but that's being really picky, especially at this price!

    Whilst it's true that this is a lightweight, space-saving device, the power supply is bulky but more than that - it emits quite a lot of RF noise as it's unshielded which means if you've got it anywhere near mic cables, you'll pick up quite a hum. If this unit was better shielded, it would get five stars because it's good in every other way

    Have used this already in my studio. No complaints from clients or myself. Useful and simple piece of kit for multi vocal recording and over-dubs.

    * Allows more than one of us to hear via cans when recording with microphone. Individual vol pots mean all cans don't have to be the same level and that you can adjust for different impedances. * I ran out of room so I velcroed it to the leg of the table where my recording gear sits. Its light enough not to pull away. * Can't say about longevity, only had it a short time
