I purchased this Addison Faucet sometime back (I can't remember the exact date) but it was 2-6 years ago and I have replaced the cartridge due to dripping at least three times!  It is easy to replace but for something that costs so much one would think that it would preform satisfactorily for many, many years.  If this situation continues I'll be looking for a faucet that doesn't have this particular type of cartridge.
