Has good stimulation, but doesn't stay in place very well.
Even when sitting the tabs come off.  They don't stick well.  The TENS unit stimulates like it's supposed to, but even when just sitting still the pads come off. they need better adhesive.<br /><br />The unit isn't rechargeable.  You have to use batteries.  You can buy rechargeable batteries for it.
