Focusing merely on the product (but will comment on the app later since it's part of it). I have 2 of these ovens, one on the wall and one below my cooktop. First off, they are GORGEOUS. Sleek, modern, fits our decor well. I've used one or the other daily since installed a few weeks ago. I love the touchscreen, very responsive. Lots of programs, I haven't had a chance to try them all out. Seems to do a better job at not heating up my house the way my old oven would. 

One of the selling points for me, however, was the app. I thought it would be great to be able to preheat my oven from someplace else, but it doesn't work. I put in all the information and it shows my oven, but when I try to use it the program sends me back to log-in and never connects. Hopefully it will be resolved in time, I will keep trying.
