I'd originally purchased the Opti Myst which I had problems with, also I didn't realize the water container needed constantly filling & cleaning - difficult to keep crawling into the fireplace. Electric Fireplaces were great, I received a full refund and purchased this unit. Just unpacked the box, lifted into the grate, and plugged it in. Very lifelike flame & logs, I absolutely love it - in fact I prefer it to the Opti Myst
