## Description

Review: Worth the hype - This thing definitely works. Let's start with the packaging: look at the picture, it's nice haha. Ease of installation: this was as simple as swapping out the nozzle on the X1C, disconnected the old one and used the same fan, then installed the revo. Easy peasy took less than 5min Performance: I'll say that it definitely outperforms stock nozzles. From the picture Included you can see that on the right is stock flow test and the left is revo. Revo actually finished the test while I had to actually cancel stock due to failure. In terms of quality printing from looks I would say the quality on the revo print started to fail about double past the stock. I'm excited to be able to try this with different nozzles and the quick swap as the biggest reason I got was that I could tell that the clips on the head board were starting to get loose so this will make it so I don't have to disconnect anything again. 10/10 would recommend to a friend.
Review: Best upgrade I have ever made. - When it comes to 3D printing, a successful upgrade for me often means it just didn’t make things worse. Very rarely does an upgrade actually make things better. However, this print head has set a new standard in successful upgrades for me. It’s just amazing to be able to unscrew the nozzle with my bare hands and swap it out with another of a different size in a matter of seconds. Not to mention the nozzles work extremely well just as good if not better than OEM nozzles. So very happy with this purchase. I do understand it is a little frustrating that the photos for other nozzles look like they come in a pack. I wish they would fix that, it is misleading. But even at $20-$30 per nozzle, it’s worth it to me for the simplicity and functionality. Thank you for making an amazing product!

### ⭐⭐⭐⭐⭐ very good hot end
*by J***N on August 24, 2025*

A nice upgrade from the standard bambu hot end, i was having issues with clogs and wanted this so the nozzles were more easily replaceable, so far I haven't had this one clog once, and there seems to be a larger variety of nozzle tips available for it. It fit perfectly, and my overall print quality seems to be a bit better and marginally faster since the heating is a bit better.
