I have a suite of original BambuLab hotend sizes but changing them was something I was becoming reluctant to do because I was lazy and the wear and tear on the extruder head connections. Not an issue anymore. Nozzle change is fast and without issue. I love it and even though it is comparatively expensive it is a justified purchase with the mitigation of the (non-)issues I identified earlier.

I change nozzles a lot, depending on what I'm printing. The Revo system is the easiest and fastest way to change nozzles. I have the Panda and .4, .6, and .8 high flow nozzles from E3D. No, they're not cheap, but they have worked flawlessly for the last several weeks. The Panda hotend makes using the Revo nozzles super simple and is a great upgrade if change nozzles a lot. Highly recommend!

I'm sure it can be very intimidating for most people to work on a machine this expensive. The instructions and install tips are easy to follow. Nozzle replacement takes seconds and no tools required. It's exactly what I was needing to get my family more able to be involved! I will slowly upgrade to harder nozzles as these wear out. Customer service was top notch!

I usually change a lot the nozzle and the revo system is perfect, the hotend heats great but the bambu system in my opinion is better.
Anyway i recommend a lot this hotend for those who change a lot the nozzle
