Review (3/5): Like the workout it gives.  Worked really good in the beginning. Ended up ripping in about a month.
I loved the size and the fact that you can walk around and have it around your neck. Doesn’t even look bad around your neck either. Looks like a cool necklace. It lasted me a good month before the plastic pieces began to fall off. After those popped off, I was left just chewing on a rubber that didn’t really do much. It began to rip and eventually just ripped completely.
