It says m controller has lost conetion, and I can't make it work. What do I do?

Did you pressed the red button on both the console and on the controller?

You're a life saver, Fazz! I didn't know there was a SYNC button on the controller. I got it to work.

They don't break easily, I dropped one out of a three story window once (accident) and it still worked.

 I must ask...how  did this happen?

 I don't remember precisely which site it was but back around launch time one of the gaming news sites had somebody throw one against a brick wall (on accident) and they put the batteries back in and it worked.

So they did a video about it and repeatedly chucked one at a wall, I don't remember if they got it to truly break or not, but if they did I seem to remember multiple extremely hard throws.

Ultimately any controller that can take 1 of those kinds of blows is probably at about what I would like to expect from durability for controllers....but multiple back to back is just a damn solid piece of equipment.
