Basically its a piece of crap.
Extremely poor quality audio even when played through a boom box.
On its own it is completely unacceptable. Very low volume.
I have heard better audio from $10 stuffed animals.
btw batteries were new when I tried it.

I was looking at these, you can't get them in the UK yet (well haven't seen them) thanks for the heads up. I won't bother buying one now.

As I read the instructions again to see why the message repeat delay for high trffict function isnt working I read this:
This Device is NOT intrinsically safe.
Do not use the device where an electrical spark might cause an explosion.

btw, it is a light sensor not motion sensor.

wow sounds like a super safe product may cause explosions hmm think this is one product worth passing
