Review: This represents a real upgrade. - I purchased this to replace the broken plastic extruder on my CR-10 and was essentially just looking to have the machine back in action again. This arrived complete with a number of accessory parts including a much stronger bracket than that which was originally supplied. The pieces went together well and were an exact fit for the machine. I hadn't particularly purchased this as an upgrade but the supplied parts - especially the sharper 'cog' have really made the machine feel like new. This has given my prints a real quality boost which was unexpected and I'd certainly underestimated the difference that this would make. This is a really good kit at a very good price. Buy one.
Review: Nice little upgrade for my Ender-3 - I thought whilst I needed to replace the bowden tube on my Ender-3, that I'd also upgrade the extruder to something more durable, especially since my wood PLA was starting to wear away a notch into the plastic extruder. This was fairly easy to install, and comes with replacement parts for the extruder and gear. The new extruder seem to be good quality and looks nice. My only tip for people looking to buy this is to not overtighten the screws when installing this, as it's very easy to strip the threads.

### ⭐⭐⭐⭐⭐ East to install, and great quality
*by E***C on 22 March 2020*

I bought a metal extruder for my ender 3 after my plastic one began to fall apart. I had nothing but problems with the metal extruder. I tried everything to figure out what the under extrusion problems were until after a month or trying and failing I bought this extruder in a fit of desperation, hoping that this higher reviewed one was the solution. This extruder immediately fixed the problem. Easy to install, the instructions were handy to jog my memory on what goes where (though if this is your first time fitting an extruder I recommend a YouTube video) and after it was installed it fixed all my problems. I'm very happy.
