It works but somewhat roughly made
Wow, I can't believe Alex is selling the rings on Amazon as well. FYI, I am his high school friend and who helped him design the instruction manual in the early stage of his business. In fact, I was wearing the rings as shown in the demo pictures. I am the person who actually partially influenced him to research on magnetic therapy. Back in 1991, I told Alex that that I received magnetic therapy on my earlobe for helping to improve my vision. He then started reading books on his own and doing all those experiments at home. He did not go to colleage, but like to do try things on his own. I think most people owe Alex an open mind to give it a try, just as Hillary said about Trump. I am not a Trump supporter though. Anyway, I think the rings will make you speed up metabolism, but it is somewhat roughly made. If he gets some big investors involved such as those in the Shark Tank show, they may be able to help him to improve the design and make it more comfortable to wear. Of couse, they may just laugh him off the show, if he even made to that show. I found it make me difficult to fall asleep, so I don't wear them, as I have to work M-F, unlike Alex he who usually gets up at 1 pm and live on his own schedule.  To sum up, the rings do work somehow, and a few people may feel no effect, and I believe most do. If it is comfortable to wear, I would give it 5 star rating. Cheers!
