It’s a perfect fit and works like a beast!

Very fine and practical .

I have been using this Panda Bambu Revo on my X1C for about 1 week and I must say that it is far superior in both quality and speed (due to higher flow rates) than the stock BambuLab hotend. I replaced the REVO HF brass with a Revo high temperature (Chromium nitride coated steel) HF nozzle. This allows me to print at the same temperature conditions as the stock steel nozzle and also can be used with abrasive filaments. The obsidian HF also can be used but I had this one spare. The prints have less blobs on the first layer so I suspect the filament is being melted move consistently in the REVO. Some people have suggested buying the CHT nozzles with the BambuLab-copy hotend instead that are available on AliExpress. I have tried these and found them to produce poorer quality prints and I had heat creep blockages on 2 of these. While, the REVO simply never blocks and in my opinion is a fantastic upgrade - superior quality, higher flow rates (with HF Revo), and much easier change of nozzles from 0.15mm right up to 1.4mm. Absolutely worth every cent!!!

Changing nozzles is a breeze with this hotend.
I'm loving it, even the 0.15mm one works like a charm with the AMS.
