Very well made, and goes together fairly well. The instructions are poor though. It would be nice if it had casters to move around fully loaded.Great rack. Sturdy and relatively easy to put together. Packaged extremely well. My power amp is 50 pounds and these shelves can hold at least that and more.Delivered in 1 1/2 days after I ordered. Actually fun to assemble--in spite of no instructions, and it looks GREAT!!!This shelf is extremely well made. Very studry & nice to look at. I'm very happy with this product.Outstanding product holds all my audio equipment and looks great.great service and super fast delivery.Easy to assemble, strong and sturdy, visually attractive. Holds plenty of equipment while making interconnection easy.This rack is made metal and glass. It arrived packed very well. Every piece was individually wrapped and tightly packed. It took a long time to unwrap everything. The metal is fairly thick. There are a pair of bolts at each connection point. The threads are built into the rails; there are no nuts. The dual bolt configuration really helps make this shelf sturdy but the overall cabinet will flex a little if you push on it This unit is deep and wide. I think the openings are big enough to fit any component out there. The bottom and top shelf lay directly on the foam pads on top of the rails. The two middle shelves slide into the brackets on the four corners. Inside the bracket are plastic tabs that can be turned to apply pressure to the glass which makes them feel like they are held in place. I think it is a great cabinet for the money.
