Beautiful commercial stove
I have had my stove for a few days now her are my thoughts Pros... very nice looking,I love that it's simple, no electrical panel to break. Simple led lights above the knobs look fantastic, and one light that is super bright on the inside of the stove. I love the two round burners, and the middle burner for the griddle, perfect. And it's super heavy. Somewhere I read a review that it's made cheap...umm No. Oh and the convection fan is super quiet you literally can not hear it run, but you can see it shut off when you turn it off. Now here are the cons that I found.. Its commercial stainless steel so you leave fingerprint ( I dont care, but some might) I find the oven part is lover than the normal oven= more bending over to remove your food, the last thing...the stove has a regular plug, not a flat one so you cant push it all the way up against the wall, that's poor design, but no worries we will fix it, but at this price point I shouldnt have to buy a new electrical cord for it.. I have yet to cook anything because its summer, if I find anything I'll update this review.

      Your people threw my appliances as if they just pushed with their feet of their truck and left them on the side of the road. A quarter of a mile from my house. I will never do business with you ever again!

          Best stove I've ever owned. This is a true commercial stove. Very heavy - will need help installing. Absolutely perfect. You will notice when you first open the oven door that it is heavier than lesser quality ranges. The range is very well insulated - door stays cool to the touch during baking. The stainless finish does not show fingerprints - very nice. Cook top cleanup is easy. This is the 4th range that I have bought in the last 5 years and never found what I was truly looking for until now. Everything else was subpar to this one. Things to know about this Range. 1. You will need a high volume gas hose to take advantage of the high gas output of this range. It puts out a lot of gas. 2. Cook times are done in a fraction of the normal time, so you will need to watch everything when cooking until you get used to it. 3. Make sure you preheat the oven and you will bake items to perfection. Pies are now flaky with a golden brown crust - something that I have never been able to achieve with the other ranges that I've had in the past. 4. The convection oven is perfect. My prior ovens had the convection feature, but it never gave the results that I was looking for. Likes - everything Dislikes - nothing Only had this range a few weeks, but based on my experience with it, I would recommend this to anyone who is looking for a quality commercial range at a price that can't be beat. This range exceeds all expectations.
