Great price. Nice packaging. Great quality. You get exactly what you pay for.

The parts fit perfect, great to have.

As there are 3 items in the lot, I will split it up into 3 parts: *Silicone Sock - Got the most use out of these things. They work in retaining heat in the hotend. My printer honestly doesnt need it, but it helps in keeping the hotend clean. *Heater Block - Looks like the stock block. Fits well with all-metal heatbreaks. Temperature probe and cartridge have no problems. There were screws for the heater cartridge. I did have some problems with the fact that there are no screws to hold in the temperature probe. Had to use spare screws, but it really should be included. *Heat-break - Didnt use these as I already have a pack of all-metal heatbreaks, but these are still useful as a backup. Overall a good pack of parts. Wish it came with those aformentioned temperature probe screws though.

Awesome replacement quick install would buy again

I went to use these and noticed that the heater cartridge fit into one block but not another. Same went for the throat where the bowden tube fit through one but not the other. So one set was wasted.

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 :)

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!
