Content is very good (the carrying bag and the supplied batteries are very good points), by cons, the product is packed as it is in the box (no additional protection, apart from a few plastic bags).
Once the receiver connected to the PS3 and lit microphones, the connection is instantaneous.
The pickups work very well, even at 3 meters (not enough hindsight to be tested).
I am generally satisfied, but I do have quite a disturbing downside to report: mics saturate too easily.
If I have the misfortune of the microphone too close to my mouth, it starts to saturate for several seconds (at least 10) before returning to normal.
In the leaflet, they say to sing taking the microphone 5 to 10 cm from the mouth; me is rather 15 to 20 cm I have to hold it.
Anyway, overall, it's a good product, provided to be really careful not to hold it too close.
The notice indicates that you can use this product with a PS2.
