WINSINNWINSINN 24V 50W Heater Cartridge 620 Heating Tube HT-NTC100K Thermistor 1M for Ender 3 CR-10 Sensor Heater Block V6 J-Head Hotend Extruder 3D Printer (Pack of 5Pcs)

Picked these up to replace the stock 24V ceramic Ender 3 Pro heater. I have a Micro Swiss, Micro Swiss clone from Gulfcoast Robotics (which I like better honestly), and two different V6 clones of varying quality and price points with which I am currently experimenting. The time to come up to temperature has gone down considerably; it really is a pretty drastic difference. Live monitoring with Simplify 3D the first time using these, I almost thought that the new thermistor I had installed was faulty... That's how fast the hotend heats up now.The wire sheathing and connection materials feel and look top notch. They are slightly rubbarized and have a certain rigidity that I find desirable for routing the wires. I have to tighten down the hotends around these heaters a bit extra compared to stock and another 40W aftermarket heater I had tried before and didn't like, but it doesn't affect anything. Just an observation. Will gladly spend the 5 seconds to make an additional half turn or whatever for the performance increase here.My only troublesome issue is the cable length is nearly too short for my application. I am running the printermods MDD system, and I needed to run the heater and thermistor leads across the front of the x-axis to the zip tie block with everything else as per usual with the MDD but then had go straight down and into the control box area through the small open notch in the back left. Routing the heater and thermistor this way works out well, and therefore satisfies my requirements. The wires are exactly as long as specified, so this isn't a complaint, just a bit of information in case anyone else has implemented a similar setup. I cannot comment on adequate length when running the stock bowden setup.Will probably grab another set just to have. The v1.1.5 Creality board handles the additional power requirements of this heater without any issue, and the time waiting for axes home, BLTouch initialization, and ultimately the print to begin has gone down by around 30-40 seconds with time saved from heating the hotend.

When I purchased these I did not have high hopes given the price and what they claimed. I was very pleasantly surprised when the package arrived. High quality, mine gets my hotend to temperature very quickly. I have only tried one of the heaters from the package as it has not given me any issues but given the exterior quality of the heaters, I can't imagine the rest will have an issue. Fit in my E3D V6 with no issues.

Replaced my stock heater on my 3d printer with this one. Temperature is achieved quicker and holds more stable.

The heating can be a little inconsistent as far as holding temperature. It will vary +/- 3°C but it heats up quickly and install was easy. Just remember to get some kapton tape. I used this on my Ender 3 pro.

These seem to be pretty high quality heater for the price. They have great feeling wire and I love the white color instead of the red that 40W heaters have. Only time will tell how long they hold up but if your looking for quicker heating times, the ability to maintain higher print speeds, or like me you need to overcome a massive amount of cooling airflow then these heaters are a great solution to try.

Works great! Voltage is marked on the cartridge itself so make sure you have the correct one before installing. Heats up faster, if you ever have any plans to print very high temp material like polycarbonate... it just makes life easier. And with the nature of 3d printer modding, any product that comes with spares is an A+ in my book.

I bought these because I needed to replace the 40-watt heater on one of my Ender 3s. This version is much more durable and heats faster than the old one. You don't need to physically alter anything or change the firmware to make it work, but you will want to run a new PID autotune to prevent temperature fluctuations during prints.

So I ordered these cartridges as I was impatiently waiting for my cartridges from TH3D and the one I used heated up but there was an issue. The issue I encountered with the cartridge was that the temperatures would begin fluctuating after approximately 20 mins of starting a print. These fluctuations were at most 6 degrees from a set 220 degrees Celsius. I even did longer PID tunes to attempt to get the fluctuations to stop. A steady temperature was never reached once the fluctuations began and I did a few prints to confirm that it was replicable. I received my TH3D cartridge yesterday and swapped it in and can't replicate the issue with said cartridge indicating that the issue was with the these cartridges and not my setup. Playing devil's advocate it could be that the first cartridge I used was faulty as I did not test all of them.

Quality heaters for the E3Pro. Reasonably priced.
