I have had this microwave in my new house for almost a year.  It's very reliable and also very powerful.  In many cases you may need to cut down the recommended times (like when popping popcorn :).  
My old microwave had a one-button push for minutes, where you could just push "3", for example, and after a few seconds a 3-minute cooking timer would start.  This one works differently, so it took some getting used to (you have to punch in 3-0-0, and then Start).  The 30-second button comes in handy.  Overall, I'm quite happy with it.
