First, this TENS unit works as advertised and has multiple options.
However, this TENS unit also has two dangerous design flaws. It has a touch screen with a lock button. The lock button is turned on by simply pressing the button, fair enough. BUT, to turn the lock button off, also only requires a simple press. Meaning it is very easy to accidentally turn the lock button off and activating all other buttons unknowingly. Other TENS units I have used, the lock button once activated, requires either a double press or a long press to turn off. This makes it extremely unlikely that you would accidentally turn off the lock button.
If that wasn't a bad enough problem, the second flaw completely disqualifies this device as a safe to use TENS device. The lock out button DOES NOT LOCK OUT THE INTENSITY CONTROL!!! That's right, even if you have the lock out button activated, the intensity controls are not locked out. You can accidentally change intensity from 1 to 10, MAXIMUM SHOCK!!!
Think about it, you are relaxing. You are using this TENS device to block out some neck pain. You setup this TENS device for Mode 3, a very subdued shock, say 3 intensity. You set the lock button, lean back and relax. You reach for the TENS unit to set it by your side and accidentally move the intensity button to 10! Ouch. Or, accidentally hit the lock out button, unlocking the other buttons and hit one of the preset buttons, and instead of the subdued shock setting of mode 3, you hit one of the presets, some of which give a very sharp shock.
This is the only TENS device I've used that has this design flaw and my advice, buy any of the others. This TENS unit is not safe, period.
