Query: good shave, durability an issue?

I bought this shaver after having used other Remington models before and have been generally satisfied with the quality of the shave. The feature that specifically drew me to this model and other Remingtons previously is the pop-up beard and mustache trimmer. However, I've had this one less than two years and the trimmer has completely failed. The cutting heads are easily replaceable but apparently not the trimmer, so I'll have to replace the entire unit. That said, I'll probably go with this or a similar model.
