        Beautiful Electric Range...
        My electric range arrived earlier than expected so that's a plus! Thank the Lord! Installed myself, with the help of Jesus; made sure that I got the proper plug before it arrived. Thank God for the user manual to set the clock & figure out the other functions. I pray that the good Lord blesses my home with many great meals made with this appliance.

          great stove top layout
          We couldn't be happier with our new range; large burner is on left side which is perfect for our kitchen layout.. Amazon delivered and I had to unpack and install. but not my first rodeo. I had it up and running in about an hour. the next day I relocated the anti-tilt and adjusted the height for level and tightness to the countertop. i then turned on range and marked critical times to warm up to 450, so we would know preheat times. Since I retired, I do a lot of cooking. can't wait to cook for Thanksgiving. which by the way, our previous stoves oven failed one week prior to Thanksgiving, getting the range Sunday night saved Thanksgiving for us. So thank you for offering the range through Amazon.

              Looks beautiful
              We have an awkward area for a range. Despite best measurements we had to buy and return a range that wouldn’t fit. This one is full size interior but fits shallow depth counter. Doesn’t block drawers on side at right angle. Burners heat up fast! Was east and intuitive to set the clock. So far very happy!

                perfect fit
                I bought this for my small kitchen. It is a perfect fit. I am thinking about buying a cosmo microwave for above the range.

                  Beautiful range
                  This is a beautiful addition to my newly remodeled kitchen. I have tried several of the features on my range and for the most part have functioned properly. I have given this Range four stars mainly because the instruction manual needs to be more detailed. The fan runs continually during the normal bake cycle not only on the preheat as described in the booklet. Also, when the timer is set and the oven is set for baking the timer begins to count down during the preheat. The food is not in the oven until the preheat is complete so why would the timer start beforehand? I have tried unsuccessfully to set the timer once the food is in the oven but I get a two beep error. I will contact Cosmo for clarification. This item is packaged very well and the 4 prong cord is attached. The installation process was straightforward and easy.

                    A VERY NICE RANGE!
                    This range is first class! The elements heat up quickly. It would had been nice to have a larger element for my 14" pots and pans. The oven is awesome! I'm in the process of figuring out were to position my shelves, for my baking needs. Overall, the range is gorgeous and works very well.

                      Commercial Grade - Commercial Quality
                      We are so happy to have our new range installed. The delivery was so simple, straight from the manufacturer. Really well packed, easily unboxed, plugged in straight out of the box and working. (Some protective films to remove, that’s a good thing :) The burners heated super quick with very easy to use knobs. Btw, knobs are so great even for an electric range. The baking was even and made it easier with the temp sensor (plug into the inside of the oven). We didn’t even know it came with that feature.

                        Many oven features
                        Cooks well. The oven has many more features than I read about which was a pleasant surprise. Plastic scratch film on the front two corners was difficult to remove. Cook top steel trim scratches easily. I wish an additional rack was included. Oven controls turn on when my stomach touches the control panel while cooking. I solved the problem by locking the oven control panel. Customer service was easy. I called during installation. There were warnings included about the plug outlets. Found out if your old range is over 10 years old, the new plugs probably won't fit in the old sockets. Fortunately for us, our contractor friend who helped with installation, can do electrical work and put in a new socket. Overall, I'm pleased.

                          Sleek, stylish, super
                          Full disclosure- I found this oven based on looks at first because I wanted a slim-line stove that didn't look like a Honda Fit. (I hate how most modern ovens all look like bubbly cars!). All I was looking for was a nice, square electric stove. Then I started reading the reviews and my mind was quickly made up. I ordered, it was delivered, and installed easily. It heats up in seconds, works perfectly, and is gorgeous to look at. And I love the built-in thermometer which looks like I'm plugging in a guitar amp! :) The warming ring on the cooktop is amazing too - especially when you've got four pots going already and want to keep something toasty (but not burnt.) Get this simple, smart oven and don't waste time with the ones twice as much (but half as good).
