    Yeah I’m reading these good reviews and my mind is blown because I got mine and it’s not compatible with my ender 3 pro AT ALL. The hole for the thermistor is not wide enough or deep enough for it to even fit in the block. I tried to drill it through but the hole for the thermistor then intersected with the hole where the the nozzle and filament pathways are. So there’s no possible way to use the block with a thermistor while also being able to send filament through it. Well, I’m happy all these other customers got ones that worked, wonder why mine were different...

    So far only used one block after stripping out my original one on my Ender 3 Pro. There was absolutely no issue with alignment for me and everything has been working the months since with a lot of printing. However I am knocking off a star for not having any extra screws. I had almost lost my original screw twice during the swap and not having an extra wound of been very inconvenient and aggravating. If they start including the screws this would be a near perfect product in my opinion. Update: Even after about a hundred additional hours of printing and months later they are still holding up great. Not that its surprising as they are just chunks of aluminum after all. But there is no difference I can tell even with thousands of hours of printing between these and the ones I replaced. Flow is good, swapping nozzles is good, temps are good. It just works :)

    These heater blocks do not fit the CR-10 V3. The screw holes do not line up.

    If you want to keep taking apart your hot end, this is the product for you. Filament melts and comes out of everywhere except the nozzle. Stay away

    Horrible!!! The hot ends I received didn’t have the thread for the screw to be threaded correctly. The pieces didn’t fit together right. Now I have one printer down with filament all over my hot end. What a mess!

    really easy installation, just remove the wires pop it in and reattach. I always love installations you can do cold

    tldr; WARNING! THESE ARE NOT 100% SILICONE SOCKS -- WILL SMOKE/BURN. Installation of the block and throat were easy. Everything seemed to line up. I used screws from removed old print block/heatsink. I brought the temp to 260 and a greyish smoke can easily be seen. The silicone sock smokes (burns) like crazy. I thought at first, my installation of the heater/thermistor was bad and maybe it was the insulation of the wiring, but I removed the sock and heated up the heat to 260. No smoke when sock is off. I looked up what the safe temps are for normal silicone socks and read it was 300. I was well below that. I thought, maybe there is some residual oils/soaps/etc from the manufacturing process. So, I put the sock back on and heated to 260 and left heated for about 10mins. After 10mins, there was still smoke coming from the hotend. I tried all 3 socks. Same results. In conclusion, the material used must be made with a mixture of silicone and something (maybe rubber?) to lower the manufacturing costs. Now Im wondering about the aluminum block and the stainless-steel throat purities.

Optimal design of heatbreak

Brand new stainless steel material with high-purity decreases the loss of heating block temperature by reducing heat conduction, and at the same time, it transfers its temperature to the radiator, which ensures the production stability.
