You would think that since only thing to assemble is add 4 legs that it would be easy peasy... but no it was almost impossible.  The four legs were hollow and small. You had to stick the screw inside the ￼3 inch hollow leg and attach it to bottom of the fireplace .  Trouble was the leg was so narrow that once you had the scre w stuck in the hole you had to take your finger out and pray the screw didn’t not fall out before you got the screwdriver into the screw and start turning. By the 3rd screw we finally got a very small piece of tape and taped the screw onto the end of screwdriver and problem solved.  Instructions were also vague about where to position the placement of glass rocks.  Fireplace is very small as per description but we placed in a 10 x12 room and it did make it warm if door stayed closed. Only on or off and same with the flame.  I also wish it had a remote control but with using in a small room you should be able to reach it when you want the heater on .
