BIQU Extruder Pulley 36Teeth Bore 5mm Stainless Steel Drive Gear for 1.75mm & 3mm 3D Printer Filament (Pack of 5pcs)

Greatest

Worked good on my cr-10s

These seem like they will hold up better than the brass. They have two set screws and were an exact replacement for what I had.

Fixed my Maker select V2 with these, dont know if these match the factory gear as I dont think mine had a factory gear in it when it failed. But it matched whatever mine had. Only critique is that the gears seemed like they got banged around in transit so there were some light existing marked/gouges on them. I suspect its not an issue, I just used the one with the least and it worked great.

I used this as a last ditch attempt to fix the extrusion on my Tronxy P802m. it fixed the extrusion problems and now i get perfect prints every time! i will be ordering again when i need more!

Works well

I got this as an upgrade to my CR-10S, which seems to work a lot better than the factory brass one. After installation all you have to do is calibrate your E-Steps, which I used a video by SanTube 3D off YouTube to explain the process. Afterwards I would suggest re-flashing the firmware with the new calculation of your E-Steps as some printers may vary, so you wont have to keep putting the E-Steps in every time when you turn off or restart your printer.

These wheels work and fit perfectly but they wear out quickly. I do a lot printing and have to replace them every few weeks. If you dont print 24-7 this might not be an issue for you. I dont mind having to replace them because of how cheap they are. I like to clean and lubricate my printer regularly so I just replace the wheel when I am doing my preventative maintenance.
