Sereni Stim™

not as beneficial as i thought it was going to be

works a treat

This is not worth $1.50, much less $99. It’s nothing more than a crummy, substandard TENS unit to hang uncomfortably around your neck. In a completely different galaxy from what they promise. It’s complete junk, a waste of money, and a waste of time. I’m actually embarrassed I paid for one.
