This heavy box was well packed and the instructions were very clear. The wood looks high quality and all pieces in pristine condition,, including 2 glass doors.. All parts were well marked.You will need a good quality philips head screwdriver (preferably a drill), as well as a flathead screwdriver to tighten the screw locks. They supply a small Allen wrentch, but its used for 4 screws, all of the rest are Philips. I'm a novice at this, it took me about 2 hours, but really found it easy to assemble by following the instructions carefully. It has to be easy if I figured out how to put it together by myself!ISSUES: Tricky to get all the top cover pins aligned so the top was flush to the body of the unit. Also, the fireplace was difficult to secure the way they direct you, as it was impossible to reach the inside screw holes, so I skipped that and just supported it using the back clamps.The instructions were vague as to which direction the upper magnet piece went for the doors.My philips screwdriver stripped trying to attach the metal plates for the magnetic doors. Get them flush, for If they stick out even the slightest, the door won't connect to the magnet correctly and comes open easily.There were no predrilled holes in back of the unit to screw in the 2 backings, so I hammered them in, as they gave additional stability and were important to attach.REVIEW:It looks beautiful in my room. Yes it's a slightly fake looking fire, but it is pleasant and relaxing. You can always purchase a different insert if you prefer a more realistic looking fire.Very very happy with this unit and recommend it. A terrific bargain!
