Product review (3 stars): It works great but does not last
After cleaning the cooktop with the companion cleaning product, I applied this protectant.  The top looked like new but a few spills later it still did not just clean up easily and required a repetition of the entire two-step process.  This became such a nuisance that I moved my one-month old Kenmore stove into the barn and covered it with a tarp, then dragged in my 10-year old GE Calrod burner stove. Voila! No more special cleaning or protecting.  The fault is probably less with this protectant than with the whole concept of ceramic stove tops which look great but are a maintenance nightmare.
