    Glitches, but nice
    The range was installed almost four weeks ago. The day after installation, an electrical malfunction (including sparks!) made the stove inoperable. We have been regularly calling the polite Cosmo support service, but as of today, despite promises, no new part has been shipped, and no repair made. This is unacceptable for a stove of that price.We will update this review should it ever happen that we have a working stove.Edit: Aug 17, 2020. The part was shipped, and last week a tech made the repair: the stove is working. Unfortunately, neither the tech nor we noticed that there was an adjustment to be made to the piece. There is also another unrelated door/shelf adjustment to be made (which we only noticed when we baked), and polite Cosmo support service is saying that they will resend the repair person. Again, we shall update this review ...In the meantime, the [beautiful] stove feels solid. However, when the oven burner ignites, the removable concave sheet at the bottom inside the stove flexes with a loud clang and jumps off of the rim on which it rests. Cosmo was aware of the issue, and suggested one turn the sheet upside down. Instead, we tried placing tiles on the sheet to weigh it down in place, but (edit August 21) it's better first to put a large rigid metal baking pan (which came with a previous stove), and then put the tiles in, to protect the Cosmo sheet from scratching.Edit December 15, 2020. We do like the stove very much - but there were the glitches. Our final 'fix' to counter-act the sheet at the bottom of the stove flexing and flying off was to weigh it down with a thin cast iron barbecue grid. This holds the sheet down, and takes the least space. Secondly, the tech could not fix our 'unrelated door/shelf adjustment ' issue: it turns out the shelf support had been screwed (a little too) low on one side. Cosmo offered a 10% rebate = 'partial refund,' which we took. We shaped a piece of heavy wire and placed it between the rung and the slide-out shelf hook to level the shelf - the issue was that if the shelf was on the lowest rung, the shelf would scrape the glass door when sliding out. As I have recorded/implied, the service dept. was very nice, but it did take patience and persistence on our side.Edit October 2022. This is the nicest stove we have ever had. Further remarks: The stove-top burners are very hot, and sometimes it's a good idea to place a 'diffuser' below the pot to protect against burning. We have never used the timer. Updating from 3 to 4 stars, with the last off because of the 'glitches', as described above.

    Reviewed in the United States on May 24, 2020
    I would like to say I LOVE my stove, but we have had issues with several parts breaking in just over a years time. Cosmo is not timely to resolve any problem, including the free gift that was supposed to be sent upon registering warranty (never received despite several inquiries). Oven thermometer broke and Cosmo has yet to ship correct part to have the unit fixed, leaving my family without a stove/oven for over 10 weeks. Distressing ! Would return if I could.

    Reviewed in the United States on September 19, 2020
    This is a well built product. It is electronics free and has the look and feel of a commercial stove. Just have used it for about a week and I expect years of great use. I am a serious cook and this is the best stove I have had, currently using a high end commercial stove at home and this COSMO stove is now in my home in DownEast Maine.
