excelent product, I use it for live performance recordings and in the studio, have been an audio engeneer for over 10 years and both my brothers have been audio engeneers for over 15 years, worked on several recording studios and now have my own small production/recording studio. This product does exactly what is ment to, no hums or noises, great gain control with a lot of range to play with, individual phantom power. Construction seems pretty good. Of course is not the sound of a tube preamp, but hey, is not tubes. But still sounds preatty amazing, to be honest I'm pretty impressed with this product, it exceeded all my expectations and you can't beat the price.
