“Very convenient for connecting the 30 and 60 led per meter strips without any soldering.
It won't fit with the 144 LED per meter strips without considerable modification, those strips are wider (so you have to cut off the edge while avoiding knocking of the resistor) and there is not enough space between LEDs for the plug to fit.
I did manage to make it fit (with the 144), but it requires a lot of work and the connection wasn't as reliable.”
