Very long lasting, but not perfect.
We had this washer/dryer stacked set for what seemed like an eternity. It completely functioned, and washed clothes very well. It was very durable, and lasted for years and years. The problem is that when it does get bad, it is extremely expensive to fix. This thing happened with mine where it started sounding like a 747 jet when it was towards the end of the wash cycle, and it was too hard to fix it. We just ended up getting a new one.
