Yes! I've read a lot about users that use the HDR. Everyone that has got any result at all did so after a meditation session with the HDR. There are claims that a few have achieved physical time travel. But the majority of successful users do claim it enhances there ability to astral project. HDRKid is a member on this site. And most of his stories are from time travel astral projection. But he has made quite a few successful predictions about future events that came true. I guess his ability is enhanced through the use of the HDR. So don't fool yourself into believing you can do this without first developing your astral projection skill. Not everyone can run a 4 minute mile either.
