> 24 hourSo 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 :)

> 24 hourThese do fit correctly and function good but they do not give you the set screw for the heater cartridge or the screw for the thermosistor or even a new set to hold down the block. so if either of these screws are messed up on yours dont order these you will not recieve any screws at all.

> 24 hourGot me up and running again, but the threads are crap and lose. The socks dont fit so well. I guess I will use them for making nozzle cleaners or something.

> 24 hourthis heat block would be perfect but i had huge problems with that little aluminium stem that threads in it leaked so much filiment that it ended up adhearing all the bolts and screws to my fin stack now i have to buy a whole new extruder head and heating element

> 24 hourYeah 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...

> 24 hourI bought these for my stock Creality CR-10 v3. They dont fit 100%, some machining is required to get a perfect fit. As they are the block has to be really close to the heat sink and the nozzle looks like it is sticking out more than it needs to. All in all, it works fine but is not a perfect fit.
