This DI Box works as advertised. It has a great set of features such as dB pad, stereo/mono, phase and other switches. Even though it doesn't work with phantom power as stated In the product web page, the paper manual that came with the product said otherwise, which made me doubt for a minute until I confirmed it by trying to use it with phantom power. Also, one of the connectors for the 9V battery feels a little bit loose in both the units I ordered. Overall, for the price, you can't get a better product.
