Hard to find a 3 port, works really well in my commercial truck, would by again, like the 3 on off switchs, I great job.
Seems a good little unit. Easy to install (diesel engine} and quite accurate throughout the R. P. M. Range.
No instructions on how long you need charging, l turned it on and red light came on ? I ordered two and don't know how to operate it. SMH.
You can feel the stimulation through the whole pen. I thought it would only be at the tip of the pen that touches the skin. Maybe I got a bad pen but not worth the money I spent.
