This is actually the only RC I use now. For instance the other day I was reading an article on the internet and at the exact same time I read the name Dylan, the television in the background said, "Dylan." I immediately RC'd. One time my friend tossed a ping pong ball over his shoulder just throwing it away. It hit a chair behind him and bounced right back into his hand before he had a chance to move it. I RC'd. I RC every time something out of the ordinary happens (odd, strange, lucky, etc.). I also RC every time I see a beautiful landscape/scenic view/etc. They have worked well for me thus far.
