Review on 🔥 Enhanced Titanium Thermal Heatbreak Upgrade for Creality: Improved Performance and Heat Efficiency by Dan Bobbert

I have changed my rating from 2 to 3 stars. That's why. I have a bowden printer (as well as an ender) and one of the most important things is retraction. You have to keep the draw low (2mm or less from what I've read) or the extruder will suck the hot plastic back up the tube. Not an issue with the PTFE liners as they are smooth, but an issue with the metal) so my issues were probably due to being a beginner rather than the thermal break itself. If I find this to be true , I will update. The machining looks good so I'm sure the product is well made, the finish is fine and the fit is fine. However, I don't know if they are actually non-titanium or if the thermal break part is too thick (the thinner the wall, the less thermal creep), but in fact they perform worse than traditional stainless steel thermal breaks. Which, considering they're supposed to be titanium, should mean they're better/faster at dissipating heat through the heatsink. Consistently after turning on this thermal break I was able to print 1 to 2 layers (depending on the size of the model) and it stopped extruding as heat penetrated the top and melted the plastic in the 'cold' zone. Tried keeping my heat (for Pla) full but to no avail. I set the default thermal break and print normally again. I would avoid until they fix the issues.
