yap,i think "witson" is a new company and their price is lower than " dynavin and hualigan"

i just wanted to know if any buy from them...

and how their units are,and how they respond...

so the OBC is the button on the right down "bc"?

hmmm,so thats why they have to keep that!,,but do we have to?,, i never checked that obc ....i just look at the front where the miles are for any problems...

thanks
