This machine worked like all the others I owned prior to owning this one. The new gizmos and gadgets and fancy buttons make everything seem great. Then after a few washes you notice that nothing has improved in terms of the quality of the wash. Don't get me wrong, the clothes still come out spotless with only a few faded marks. But it's nothing to go home about. There hasn't been any noticeable improvement in the overall quality of the clothes to the machines I owned prior to this. The timer is loud when the wash finishes and is a good feature if you wash during the day. I wouldn't suggest washing overnight though. I don't know how easy installation is, since I had a local warehouse install it for me. For professionals though, it didn't seem to take them very long. It does contain a lot of clothes though, I was impressed with that. If you have a dinosaur machine that is loud and terrible, I suggest getting this machine. However, if you have a machine from recent years, I suggest you go with something else.
