          The flames & crackling were as authentic as you described.

          Extremely easy to install. No guilty conscience about contaminating the environment or leaving an **** footprint. Looking forward to enjoying our previously unusable fireplace all year long. But, we received no user's manual, no instructions for attaining the App, and there was a dent on top which lead us to believe this might have been returned by another customer. Left Modern Blaze a voice message last week. Have not heard back.

          New home construction option

          I selected the Opti-plex fireplace cassette for the fireplace in the new home I am building. The house is almost a 'passive house' design being built in Virginia. It is very tight and well insulated, with a heat pump and ERV system. I did not want to compromise the envelope with a vented fireplace. I wanted something looking much more authentic than an electric fireplace and not behind glass. I also did not want to be buying biofuel endlessly. A water vapor fireplace filled the bill perfectly. Unfortunately there was no showroom to see any of these in operation. I selected the Opti-mate based on its specs, features, videos and price. I did not care for changing the flame color as that destroys the authenticity, but the sound would add something. I ordered the cassette early and set it up in the basement of my current home to see it first hand and to assure that it arrived in good condition. It is just what I want! Beautifully authentic looking random and non-repeating flames, safe and negligible operating cost. Even adds a small amount of humidity to the home when it is likely needed. Now just to design the 'fireplace' to show off its flames to the best advantage.

          very nice product

          Just opened the box and in 5 minutes I'm watching a wonderful flame. Can't wait to build my fireplace to put in in. Looks great even on Mt kitchen island
