The question….why after 15 years and nearly 5,500 trouble free cycles would you even consider changing brands?
Do you think quality control in brands doesn’t change over time?
Do you think brands only get worse?
A lot of things change in 15 years. Today another brand may be heads above what was available 15 years ago. I am presently shopping (for a totally unrelated product) the old one served well, come to find out I can’t replace it with a “like” replacement. Things change, both good and bad.
