I bought this a few weeks ago and so far, it's pretty good.  We had our old microwave for 11 years so this is definitely an upgrade.  A minor complaint is that it is slightly less powerful than old one so it cooks a tad slower and we're learning what adjustments we need to make.  Also, the defrost cycle is a bit different and again, we are learning how to adjust.  Also, some difficultysetting up LG ThinQ but we also had this problem with our LG Refrigerator.  Not a big deal but it is a feature that is so far not usable.  Really nice feature is the pull-out vent that allows extra coverage for stove top venting needs and works pretty well.  Overall, this is a pretty darn good microwave and another win for LG
