It does exactly what it says on the box. The XLR cables aren't super duper quality but are OK. The power supply itself is identical to the one you get as a standalone. As such, it is questionable whether the "kit" justifies its price tag as it would be easy to assemble the same collection of bits and pieces... and I'd guess for less money.
Overall, it's what is needed, and is purely the value for money aspect that I have reservations about.
