My LG range (LSE4616BD) was delivered a couple of weeks ago. I've used both the range and the oven numerous times since.  On "Bake", I've found I had to leave some things in longer than recipes called for.  On "convection", the cooking time is a bit shorter.  Everything has turned out perfect.  The induction range is amazing when it comes to heating water (or anything else).  So quick.  
The "extension" that attaches to the back of the range (to cover gaps between range & countertop) is a little weird.  We raised the range so the extension would sit on the counter top.  There were no written instructions on how the extension should work, so assuming we did the correct thing.  Had they made the back of the range flat, the extension piece would not be needed and it would have been better.
