I have 3, no problems, one is going 2 years strong almost (micro), one 6'9 micro and one 7ft11 flipping. Im pretty careful with my gear and I dont hookset excessively hard.
I have had friends break guides off the micro rods, but I know one has broken rods of various brands (rough on gear)
The other, I cant say how he broke the guide, but I do notice the 2nd guide from the bottom is the one that seems the most suspect, even on the replacement rod.
