I bought this product in December of 2020.  In March/April of 2021, the icon pictures above the knobs had started wearing off.  I had kept with the recommendation for cleaning and was surprised to see them coming off so soon after purchase. Also, it seems to take a long time for liquids to heat up.  The gas line was checked and was done correctly so don't understand why it takes so long.  Didn't have that problem with gas ranges in the past.
