Please… FIX this misleading description on your sale page:
I’m really frustrated to bought these and realize that it’s need “special” DC power supply, for item rated as DC 12V!
You have several complaints 10 months ago, yet, no shame to fix that and cheat on your customer.
If the item can’t be use with regular DC power supply you should sale it in one package.
And, FIX that wrong description. Your wrong advertise wasted my money and time.
