Well we haven't had it that long - roughly 2 weeks so I can't remark about performance too much.  I can say that I love it - we had a refrigerator that was from 1986.  This is just awesome.  Love the space, the extra door for pop, the extra drawer that I can use for pop, lunch meats, water or just change temp and have an extra door for the freezer.  Love the BALLS OF ICE.   Havent figured out that yet - manual is complex but I'll get it soon.   Love the outside, no finger prints.  It's elegant looking, water tastes great - now I have a filter.  My old one didn't have a filter.  If this holds up as long as my old one, it would be fantastic....thank you LG.
