So everything definitely works as advertised. It's a fully functioned cooktop with all the features you could want. My absolute favorite is rapid boil. There's nothing worse than waiting for water to boil when you want a cup of tea or are trying to make some pasta or noodles. This is definitely a huge timesaver for us. I also loved the sync elements. We have a big long stock pot and having the heating elements sync makes it way easier to get a consistent temp throughout your pot. 
I tried the smart things and wifi connectivity, but I did not find it a useful feature. Maybe for some, but on a stove it just seemed like a needless extra.
Now one critical thing would definitely be the sensitivity of the touch controls. If you even get a drop of water anywhere on them the whole stove shuts off. It's really annoying so now we just have to lock the touch pad whenever cooking.
Other than that it's a great stove.
