> 3 dayThis works well in my Prusa i3 MK3S. Theres not much more to say than that. It replaced the one that my printer came with after I broke the connection to the old one when trying to hot tighten my nozzle. One thing to note is that I was sent a white one, not a red one as shown. I dont know if the items description says colors may vary, or not. And, really, how much of the cable do I see? And, really, do I even care? Also, Ive noticed that the hot end tends to shoot past the target temp by about 2-3 degrees C before settling back down. I dont remember if the old one did that, so Im just assuming it did, and that this one is no different.

09-06-2025Genuine cartridge. If you know what your buying, you will know what to expect and that this image is not right and is just the one pulled from the e3d site. This will be white and will not have a connector, it has the ends crimped into individual tips (as it comes from e3d). I got this for my Prusa Mk3s where I unscrewed the connector of my old cartridge and screwed this one in. If you are worried about it being genuine, payattention to who the seller is, not just that its shipped by amazon. I bought mine from AmznExperts who is an authorized dealer listed one the e3d site.

> 3 dayI made sure I bought from the vendor others recommended to get a legit one. Works well when I needed to replace my heater cartridge on my MK3s. Would buy again if I need a replacement.

> 3 dayIt doesnt look like the photo and it looks used. I seriously doubt its “genuine” anything but as long as it works its whatever.

> 3 dayWorks great, but was thrown off when the heater supplied was white, instead of red. I order lots of parts directly from e3D and this is the first white 24v 40w heater that I’ve encountered. Seller might consider updating the info or product image.
