Every time I've tried it I found bionic reading rather distracting. Perhaps it can help some people, but it certainly doesn't help me. I'm not the only one, some small surveys seem to conclude that on average there's really no advantage to it.
Even if the method works, the fact this whole hype was started by a company that patented and trademarked the system makes it rather suspicious to me. It's hyped up by a startup all over the internet but I haven't seen any scientific proof that there's any merit to it. This smells like a scam to me.
