I purchased this hotend for my Bambu Lab X1C with my own money at retail pricing. I also have the Revo and stock hotends for comparison. I purchased a 0.2mm brass plated nozzle and the 0.4mm High Flow CHT CM2 hardened tip nozzle.
Prior to purchasing the Micro Swiss FlowTech hotend, I asked customer service if it would be compatible with an aftermarket cooling duct and they responded within a short amount of time, that it would be.
Positives:
+ Impeccably constructed. Very high level of quality control.
+ Proper installation documentation with tips for optimal usage.
+ Customer service is reachable.
+ Made in USA with fast shipping times
+ Multitude of nozzles sizes and material compositions available
+ Easy to swap nozzles and included 3D-printed torque wrench insures proper installation
+ Ample length of wiring to reach hotend circuit board
+ Nozzle heats quickly and evenly
+ Compatible with Biqu Panda Jet cooling duct
+ Increased flow rate
Negatives:
- Some popular nozzles were not in stock at the time of purchase. However, the email notification system when items were re-stocked was functioning properly, and I ordered them once I received notification.
Comparison to Revo:
+ 60w heater, heats very quickly and generally overshoots set temp slightly before stabilizing
+ Availability of different nozzle sizes and nozzle materials (brass, hardened metal, and diamond)
+ Prints well when filaments are tuned
+ Can be purchased from Amazon, but I ordered mine from overseas
- Spring tension system for nozzle installation is not a bulletproof design and can bind if any filament happens to leak
- Wiring is very tight, with less length that factory Bambu Lab hotend components.
- Nozzle anti-stick coating on my 0.4mm hardened metal nozzle not nearly as good as expected
- z-axis and individual filament settings must be re-tuned to get best results
- No way of knowing proper torque when installing nozzles
- Poor to little documentation.
- Very poor customer service when asking questions.

I am an amateur 3D printing hobbyist and based on my use case, I would recommend the Micro Swiss FlowTech hotend to my friends and family.
