QVC is the only seller of the Cooks Essentials brand, although it is identical to other 'designer chef' products manufacturered by Salton. There may be a problem with obtaining replacement gaskets in future, but since this brand only has a 1 year warranty, that may not be an issue. Take care, those "negative reviews" should make you a tad suspicious about shelling out that much money.
Check the psi settings carefully, Cooks Essentials has used a non-standard pressure... I think 13psi, but that has changed as new models are marketed. The standard is 15psi. This is important because pressure cooker recipes, including those in my new cookbook -- LOL... I know, shameless plug -- have conformed to that common standard for almost a hundred years. Not that you can't do the math and try to make adjustments, but the extended cooking time can produce some disappointing results, not to mention that defeats the primary purposes of pressure cookery... speed, energy savings, and preserving nutrients.
Like all electric models, there are imitations, fewer safety features and the user has far less control options that restrict what recipes can be cooked. The owner's manual clearly states "... metal foil packages, or utensils must not be inserted in the appliance, as they may involve a risk of fire or electric shock... To reduce the risk of electric shock, cook only in the Removable Cooking Pot." That pretty much eliminates a huge category of recipes that use all kinds of insert pans, which are common in many wonderful pressure cooker recipes.
Have you looked at today's new, modern stovetop pressure cookers? They are nothing like the old fashioned variety you may remember from the past. These are not only top quality pieces of cookware that will last a lifetime, but they are totally reliable, goof-proof and very easy to use, and there are no limitations as to the recipes you want to cook.
