LANKEGU 5 PCS Upgraded Hardened Steel Nozzles, 3D Printer Accessories High-Temperature Resistance 0.4mm Hardened Steel Nozzle for AnkerMake M5 3D Printer

Great nozzles.

Whilst these nozzles fit both the tools and hotend physically just fine, I have not been able to produce a single 'good' print with these. For what it's worth, there's a .3mm discrepancy in length between these and the stock brass nozzles on the M5/M5C. Fine, I thought; some Z Offset tuning needed.No.5 failed prints and a great amount of twitting about with Z Offset and nozzle temps later, I'm done. I challenge anyone to get a decent first 3 layers out of these nozzles.I've consigned the rest of the packet to the back of a drawer - if the seller is graceful enough to offer a refund in lieu of a return, I shall take great pleasure in firing them over a fudging rainbow.Consequently, I've switched back to official brass nozzles, my OG offset, and everything's fine again.Don't buy these nozzles. They're buggered.
