Works fine but beware if you find any missing parts the supplier and manufacturers play cat and mouse games and then you get the "send it back with the original wrapping and contents" and send it back to france at your own cost. I ended up making my own replacement part.

Great little robot, took about 2 hours to put together, although I did take my time. Robot is sturdy once put together although I found a lot of the bolts, even when fully tightened easily pulled out when putting the individual parts together which was frustrating.
Setting up with my pc was straight forward (using Vista), haven't tried controlling it via the internet yet.
The speaker is excellent and when music is played through sounds great although does distort at higher volumes which has to be expected.
My only concern is battery life due to the fact even after a full charge dropped to half way in about 5 mins, but I guess it's a little too early to tell yet as may take a few charge cycles to reach optimum capacity.
Overall a great little gadget more for over 18's than under, unless an adult is going to put it together and set it up.

It take time to set up but when you get it working it is great fun
