As advertised, arrived quickly. I lost my charger and needed a replacement urgently. Since my Charge 4 was fairly new, I figured it would be better to pay a little more and have FitBit make one to make sure everything works properly. Works just like the original. As others have noted it can sometimes require extra attention to ensure it clicks into place to start charging, but this is no different than the original I had out of the box.
