Snake oil. Awhile back there wa quite a few fooks on this forum that had purchsed them and were in the porocess of purchasing them. Others stated they were a joke, yet they argued up and down, defending their actions on buying a joke, and how good they worked, now you do not hear a peep out of those folks. Its the same thing on all th eother forums too, the device is a joke.....and just try to get a refund........you get run around in circles to the point that you give up and chalk it up to experience.
