There's a little whine from the machine - electronics or something.


I'd say to consider one that had an on/off if it has the IR light. I bought a $150 from Big 5, and the (reddish) light is always on. In fact, when I cover the light, the goggles work for crap.

Try and see if you can test them for a few days before the sale is finalized. You may find that they're not as great as you're hoping. Or, maybe they are!
