The goggles are a dreamsign. All they do is make some lights flash so hopefully you'll see a strong light in some form. Some things that you might see are (supposing that the lights on the nova dreamers flash on and off)...

1. A car coming by flashing lights very very bright.
2. You or someone else turning lights on and off.
3. Someone shining a flashlight in your eye.

The list can go on but I don't wanna think about it anymore. The purpose of this is that in reality you should check if your dreaming every time you see bright lights or lights flickering. In the dream you see it and you think, "maybe this is the novadreamer in aciton" and you check if your dreaming and there ya go. So basically it doesn't help with recall it helps with getting you lucid and keeping you lucid (because during the dream you might see the lights again and become more lucid by remembering it's a dream).

I don't keep a dream journal or anything but I usually go over my dreams about 5 minutes after I wake up. Yeah so the goggles are just a dreamsign that you can count on.

PS: Reality checking for me is probably the technique that makes the most results (even though I don't really do it anymore). For me carrying a watch always helps...
