I purchased this around a month ago. Cooked a roast on high and it took forever for the roast to cook. My older crockpot would cook this roast in 7 hours but this crockpot took all night. Gave it a second chance on a product that was cooked but to reheat for serving (from a warm state) and took over an hour. Third chance was a recipe that should have taken 4 hours and had to end up finishing stove top because it didn’t fully cook.  This was all on high temp.
