I have purchased two of these kits and aside from three things I would suggest it to everyone. One was used to replace the cheap POS from an Ender 3(kit used now for ~150 hours in a month), one was used to replace a single-geared replacement for converting an Anet A8 to bowden style. Just received the second.
First issue. Many share the view that the included pieces aren't entirely correct... I do not disagree. There were extra pieces i did not use in both kits: a softer spring, and a brass insert that's threaded on the inside. While very possibly useful I found no need or place for these whatsoever. More concerning to me is the fitment of the fantastic yellow spring that's pictured above. The spring itself is great, but to ensure no potential issues there should be an inset in the handle to shroud the end of the spring. With the number of machining processes already done i cannot fathom the tradeoff between the spring inset and an extra spring and brass piece. Aside from that, everything else is pretty solid.
The above points to a very slight issue with the cost. In comparison to many other kits that are lower design quality this is already worth more, but without going up to a gearbox style this is about as good as it gets from amazon. for the price point I would like to see the design perfected.
Lastly, and very possibly not a vendor problem, both kits i received had tarnished or incomplete coloring and large dust and grime particles on them, including the gear teeth. All were easily cleaned with a spray of air and a wipe down, but i can't 100% stand behind a dirty, grimy, unpainted product. Either it was returned dirty, or has a low quality control circuit at the kit level. or both.
Overall, the kit is fantastic(almost perfect), and should probably be where the minimum bar is set on all printers. You will gain if you switch from a single-geared design with an idler. I only have the two printers but i would consider this kit again for a third and fourth if the need arose.

Some customers encountered gear wear problems. The solution is:
✔️Had to change the extruder e-steps from 100 to 139
Because the filament is forced to be centered in both drive gear grooves, the idler drive gear (the one not attached to the motor) is positioned on it's shaft by the motor drive dear. So, to center the idler drive gear properly, my suggestion for setting the unit up is as follows:
1) Assemble everything but do not lock the motor drive gear to the shaft.
2) Using a couple pieces of paper, shim the idler drive gear in the center of its bracket.
3) Clamp a piece of filament in the drive grooves and turn the motor a few turns. This should locate the motor drive gear in the correct position.
4) Lock the motor drive gear to the shaft, remove the paper shims, and you should be good to go.

Some pictures to help put it together
Works better than stock and MUCH less hassle than the full geared drives I have. I grew so tired of the time and effort to change the filament with my full geared drives and this loads easily like the stock drive only with two drive gears. You have to change the e-steps as the drive is a little smaller than stock. Being a little smaller diameter is nice as it adds a little torque to help push the filament through the printer. I have the CR-10 S4 and had to change the extruder e-steps from 100 to 139. Was very easy to update the firmware now that Creality is posting the firmware on their website. Look under configuration around line 589 and change the 100 to 139 and upload to the printer. Also moved the extruder from the printer frame to the control box as I noticed putting pressure on the x-axis track was trowing the two z-axis motors / rods out of sync. Some have complained of the finish of the drive but all three of the drives I got were very nice. Now using these on a Creality and a Tevo.On a side note; There are no instructions but it did come with all the correct screws and the yellow/orange spring does fit exactly on mine. I did have to put a bit of loctite on the set screw in the stepper gear. There is only one set screw in the gear, it is very short and has a tenancy to back out every few hours or printing. Very happy with them so far.Note; for the tevo tarantula I changed the extruder e-steps from 100 to 138. I am using the updated Merlin firmware in the tevo. The changes are 'around' the following lines ( I removed and added some settings so your actual lines numbers will be close but not exactly the same as mine)...984 #if ENABLED(DUAL_EXTRUDER) 985 #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, Z_STEPS, 138, 94 } // change from 100 to 138 for dual gear extruder drive986 #else 987 #define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, Z_STEPS, 138 }988 #endifHope this helps...March 2021 update;Been using three of these for a few years of HEAVY use and still love them. I have looked at a few other reviews that complain of the DRIVEN gear self destructing. Some things to consider… the DRIVEN gear is FIXED in place (no adjustment) and the bearing rides on a threaded screw (not ideal). You HAVE to leave the DRIVE (motor) gear loose and put a piece of filament between the gears to align the DRIVE (motor) gear to match the DRIVEN gear. Make sure the DRIVEN gear is centered on its axle before you LOCTITE the set screw on the DRIVE (motor) gear. If you do not do this, the DRIVEN gear will rub on the frame like the ones in the other reviews. Also, DO NOT OVER TIGHTEN the DRIVEN gear axle screw. You WILL bend the frame and squeeze the DRIVEN gear. ONLY SNUG the axle screw LIGHTLY and LOCTITE it! After dozens and dozens of rolls of filament I’ve not had any problems. Even had excellent results with NijaFlex.To the manufacturer…. PLEASE change out the threaded screw you are using for the DRIVEN gear axle with a proper screw with a shoulder for the bearing to roll on. I’ve not had a failure yet but that is the only weak link in an otherwise great design.UPDATE 01/29/22Just ordered my SIXTH for a new Ender 3 MAX. Still have the original one I bought in 2018 and after dozens and dozens of rolls of filament is shows no sign of wear.I cannot stress enough... YOU MUST PERFECTLY ALIGN THE GEAR THAT MOUNTS ON THE STEPPER MOTOR !!Leave the stepper motor gear (DRIVE GEAR) loose. Put a short piece of filament between the gears to help align the gear. THEN LOCTITE and tighten the set screw.The gear on the arm is NOT adjustable and will rub, wear and fail if the stepper motor gear is not PERFECTLY aligned.Other than that;All the parts I have received over the years all fit and were correct.The latest one (01/29/22) now has a NON-threaded spring tension collar that looks custom made as opposed to the RIVNUT the older ones used. Both work but the new collar looks nicer.This newest one also has the M3 screw pictured that is NOT threaded all the way so the bearing does not have to ride on the screw threads.Had great luck running NinjaFlex with these.

UPDATE 01/29/22
Just ordered my SIXTH for a new Ender 3 MAX. Still have the original one I bought in 2018 and after dozens and dozens of rolls of filament is shows no sign of wear.
I cannot stress enough... YOU MUST PERFECTLY ALIGN THE GEAR THAT MOUNTS ON THE STEPPER MOTOR !!
Leave the stepper motor gear (DRIVE GEAR) loose. Put a short piece of filament between the gears to help align the gear. THEN LOCTITE and tighten the set screw.
The gear on the arm is NOT adjustable and will rub, wear and fail if the stepper motor gear is not PERFECTLY aligned.
Other than that;
All the parts I have received over the years all fit and were correct.
The latest one (01/29/22) now has a NON-threaded spring tension collar that looks custom made as opposed to the RIVNUT the older ones used. Both work but the new collar looks nicer.
This newest one also has the M3 screw pictured that is NOT threaded all the way so the bearing does not have to ride on the screw threads.

That being said, here are my main complaints about this extruder:
* No installation instructions.
This product does not come with installation instructions. That said, I didn't realize the product pictures on Amazon include an installation video. I understand why they wouldn't want to pay for printing and translations when videos like this exist, then the extruder wouldn't be as cheap as it is today. But even a slip of paper with the link to the video would have been nice.
* The spring screw didn't quite fit
On the swingarm, there is a small screw used to hold the spring in place. (Not to be confused with the tension screw). In the video, the spring slips right over the screw. However, the spring did not fit over the head of my screw. Luckily, there was an Ace Hardware nearby so I found a screw to replace it. And judging from what I saw there, it seems like a common issue with minor tolerance shifts in the screw head. Half the screws I tested fit, half didn't.
* Won't Fit the CR6 SE Runout Sensor Without a Riser
If you're installing this on a CR6 SE, before you dismantle the old extruder make sure you hop on Thingiverse and print a riser for the Filament Runout Sensor. Otherwise, the hole for the sensor won't line up with the hole for the extruder. Speaking of holes, after you print the riser check that the screw holes line up on the sensor. The tolerances on my printer were a bit off, so I had to widen one of the holes to get it to line up.

So yeah, make sure you have some spare M3 pitch 50 screws lying around, and this extruder is definitely worth the money.
Works Great, But Not the Most Customer Friendly Installation

I've had some issues printing the first layer on my printer for a while, and this new extruder solved it. Thank goodness! The materials seem sturdy and well made so far, I definitely appreciate that too. Which is why my overall rating is so high. Definitely a great result for the price.Reviewed in the United States on October 3, 2021
