10 years and still going strong!
I thought I'd add to the positives on the 8140. I have had mine since Xmas 2005- I just got the first set of replacement plades/heads today. My wife thought I wanted to get a new razor and bought one that uses HQ56 blades. (my face still hurts from that single row head set) I told her to keep it and bought some blades on the web for less than most ask. I fully expect to get another 5-10 years- it's up to the battery. I do regularly clean it and reccomend doing so for thisawesome razor.
