This is an OEM hot part for the Ender 3 or 5 (and others) along with a Capricorn Bowden tube and some handy add-on parts. My Ender 5 pro started to underextrude after a few months. This exchange was a bit awkward the first time. The power cables aren't terminated, which at first glance seems cheap, but they have to be stripped to get through the mesh (Aha!). Once those wires (and thermal wires) are threaded through the ribbons, snip off the end of your old hotend's power wires (leave an inch or more). Put heat shrink tubing on the power wires, then solder the old connector to the new wires. Definitely good; no polarity. And like me, you simply replaced the faulty part with the same part. Still a good deal for all the beats you get and my back!
