These are great. Installed my first one yesterday. Working like a charm. For those complaining about the silicon covers. Your the problem not the covers. They do fit. I noticed in your photos you have them on the wrong way. Definitely not a design flaw. User error.

My only complaint is that the socks in the pics are the kind pulled back from the nozzle, but the ones delivered wrap around the nozzle. Still, the parts are well cut, fit like a glove, and I have no performance complaints in about 500 grams run through the first one thus far.

The heat block has two holes for screws for attach the heatsink. The holes between the heatsink and the block are not align and there is no way to send a screw through both holes. Returning and looking elsewhere

I need to replace these parts in my Ender 3 as cheap Bowden tube materials have become permanently burned onto the inside of the threaded cylinder. I have tried acetone and other solvents to remove the residue, but enough burnt-on material remains to make me want to replace it. The threads on the new aluminum block for the nozzle and the threaded cylinder fit so loosely that melted filament is absolutely certain to seep into the spaces in the threads. This is a poorly toleranced product and I will be returning it.

These work perfectly to replace the heater block on the CR-10s. However, they do not contain the screws for the heater cartridge or the thermistor. It would be nice to have those included as you may not have the ones from your old one (like me).

for the price cannot complain at all super easy to install just remember some thermal paste for proper heat transfer to the heatsink so the Bowden tube doesnt overheat and clog.

Awesome replacement quick install would buy again

i needed them to work and they did
