These seem to be a great improvement to the brass extruder wheels that are more standard. Fits great and I'm getting a nice consistent feed. It seems to be more durable and is lasting longer as well.

It has worked well and the little nut has not stripped out.

The Aokin Brass Extruder Wheel Gear has been a game-changer for my Creality Ender 3 3D printer. This 40 Teeth Drive Gear has significantly enhanced the extrusion process and overall print quality.The brass construction of this gear is a testament to its durability. I can feel the difference in the heft and sturdiness compared to the stock plastic gear. This upgrade has resulted in a smoother and more consistent filament feed, which is crucial for achieving high-quality prints.Installation was a breeze, thanks to the precision engineering of this gear. It fit seamlessly into my Ender 3 without any modifications or adjustments required. The teeth on the gear grip the filament securely, preventing slips or skips during printing.I've noticed a marked reduction in filament grinding and slipping since switching to the Aokin Brass Extruder Wheel Gear. This has eliminated one of the most common issues I faced with my previous setup. The gear maintains a reliable grip on the filament, ensuring a steady flow throughout the printing process.Additionally, this gear has proven to be resistant to wear and tear. Even after extended use, I haven't observed any signs of deterioration. This longevity is a testament to the quality of materials used in its construction.In conclusion, the Aokin Brass Extruder Wheel Gear is a must-have upgrade for any Creality Ender 3 owner. The improvement in extrusion precision and reliability is evident from the first print. If you're looking to take your 3D printing to the next level, this gear is an excellent investment. I couldn't be happier with the results, and I highly recommend it to fellow 3D printing enthusiasts!

I bought these to replace the original brass extruder gear. The brass one wore down after a lot of use and was causing extrusion issues. Hopefully the stainless steel wont wear anywhere near as fast.

Cheap and works. I have been running it on my Ender 3 for roughly 2 months at this point without any visible issues.

The gear fits the stepper motor as designed and does not wear down as easily as the brass gear does. This allows a better filament feed.

These are a nice upgrade over the brass ones. I only run petg and pla, but managed to wear grooves into my stock brass gear. No grooves so far in this one. I ran an estep calibration, but didn’t require any changes, so it must be the same diameter as the brass ones.

Got these to replace my worn out gear that was slipping. For the price I would have paid it for 1, I got 8! I've only had to use one of the gears to replace the original so far... which is nice because now I have 7 more as backups.
