Yeeeuch!!!! No!!!!

Don't go for this sort of toy. You're far better looking for alternatives. I'm sorry but for this sort of price you are not going to get anything resembling a microphone. It's meant for toodlers' karaokes and nothing more. It will make your video sound awful.

The two makes you should be looking at are Sennheiser and Audio Technica, both do a good range of radio mics for amateurs and semi-pro videomakers. They are a bit more expensive but at least you won't be receiving the neighbour's television, the baby-monitor and the local mini-cabs.

What did you want to use it for? In what sort of situations?
