Does anyone actually use anti-static wristbands?

    Well, if you do happen to see an anti-static wristband around (at the nearest electronic store, which is a 150m away, they sell them for around 4.5$) for your own sake, I suggest you get one. :)

    The wrist strap is supposed to keep you at the same potential as the components you are working on. This does not necessarily have to be Ground.
    You could be working on the space station far from Earth and you and the semiconductor device you are working on could be at 10,000V with respect to ground. But, as long as you are both at the same potential, there will be no current, which is the thing that causes the damage.

    So, don't think that if you are grounded, or if your PC is grounded, you are OK. Both must be. But, more importantly, both must be at the same potential. Hence, the advice to touch a metallic part of your case frequently while working on your PC.

    The third connector on the outlet (ground) is meant to ground the metallic body of an electrical equipment (washer, dryer, water heater, fridge, ...).
    This is to protect you from electrocuting yourself if there is an accidental wiring error that causes the hot wire (110V or 220V depending on where you live) to short to the body of the equipment.
    If there is a third ground connector, this will result in the circuit breaker tripping instead of electrocuting you.
    The third connector is not there to ground your PC to protect it against ESD.

    Lastly, even if you are wearing a wrist strap, you could still cause damage if you are not doing it right.
    You could be grounded and you could still zap your computer if your computer is charged.

    Well, I just attach the clamp thing to the PC case so I suppose that counts. :p

    Honestly I never wore one either. I didnt even know that static could kill still like that until about a year ago =). Never fryed anything. I just wore a wire connected to a ground in a socket, and it was all good. I connected the wire to the case too so everything was neutral. I just wanted to make sure nothing happened to my first new build on x-mas day =D.

    not sure how you missed it as most pc harware comes with plenty of warning labels and anti-static bags lol.
    static can be bad enough that people have caught their cars on fire while pumping gas.

    I have never worn one. I usually just tap side of my case first. Never had a part fail due to static and I have been building PC's since Quake2 1996!

    to say you never had a problem doesnt mean you never will. better to be safe than sorry. its cheap and easy thing to do compared to the alternative. if its 10 times or a million times, it only takes once.

    You can't even buy anti-static wristbands in New Zealand. They're pointless - just touch the metal part of the PC case when its plugged in and you're set.

    I always wash my hand thoroughly, and touch the case. I also wait for awhile to make sure it's powered down. If i think i may take some time i'll take a break and wash my hands again before continuing.

    I have killed an old harddrive before though. I pulled it out of the antistatic plastic wrap i put it in a few days earlier. Gave me one damn good zap, felt like i just got stung by a bee. It was recognized as a drive with 0 volume. :(
