Creality Original Extruder Assembled MK8 Hotend Kit Full Set Upgrade with Low Friction Capricorn Tubing for 3D Printer CR-7 CR-8 CR-10S S4 S5

My original hot end thermistor failed and the thing went into a meltdown. This new unit was super fast and easy to attach and was printing again great in minutes.

The new hot end took all of two minutes to install and worked perfectly upon its first test heat-up. My only complaint is that it did not come with mounting screws. Most people more than likely will already have them but I swapped back to this hot end after using an E3D V6 set up that did not need the old screws. I more than likely threw them out which or course is my own fault. The product comes as described, the extra screws were just wishful thinking. Fortunately I had some spares laying around. Anyway, the product works fine and takes only minutes to install. I would absolutely recommend that Creality printer owners purchase it if they need a replacement.

I started having issues with my print head showing squeeze out where it shouldn't. It was looking like a mess so I went the easy route and bought this. Plug it in, 2 minutes, level the bed and kicked off a print it's been going flawlessly for the last 6 hours. I bought 2 and plan to always keep at least 1 of these on hand for backup.

I bought this for my reality CR 10 and it’s been working like a champ have no problems. Great for the money.

My original print head burnt up on me and I needed a replacement. I went through several different vendors trying to get it fixed and found this one. Installed it and it has been working like a champ, even better then the original from Creality.Since then I've updated the cooling system on my printer but the hot end is still from this purchase. If you are having issues with your print head I recommend you get this one. For the money it is a really good product and so far I've had little to any problems getting this to Print PLA and PLA+, may now even get brave and try another filament.

The extruder assembly works well except on arrival the heat block was loose and filament oozed all over the place. After cleaning the heat block thuroughly and screwing it back together so it wasn't loose/didn't leak it ran fine for maybe 40 hours of printing and then a long print failed because the heat block seemed to loosen itself and plastic began oozing out the top again.I'm ordering a new hotend just because I don't want to deal with the recurring leaking which i've never had issues with on any other hot ends. Assembly was quite easy though.

I was having print issues and I found that it could be my original hot end had gotten damaged when my extruder arm broke. After installing this new all in one hot end the printer is back to printing as it should.

The first one I bought wasn't getting up to heat, stayed about 10 under what was needed. Sent it back yesterday for this issue and got the mail today (may have forgotten to check it a day ago) and would you know it a brand new hotend. Plugged that sucker in and bam! It heated up properly, aside from the flakes of metal on the nozzle side (maybe from machining the threads?) she works.As of 2 days ago (Apr 4th 2022) my hotend started to ooze from both sides of the heated block. So that metal from the threads was a problem, the nozzle didn't seat correctly and was able to un-screw itself and coat the bottom of the block with PLA. But wait I said both sides, yeah it seems the other end was defective? Or the threads were wrong because PLA could travel up the threads and coat the top of the block.So both purchases have been crap. I would not recommend this hotend.(Why'd it take so long to notice? I haven't been printing anything for about a year. Dreaded the cleanup process.)
