The Good: The doors definitely dress up the fireplace. Sleek modern design.
The Bad: Quality control from the factory is terrible. The door's hinges were not tightened into place, and had I not been careful, a panel would have fallen to the floor while unboxing. I had to tighten screws on both of the handles, which meant removing them from the frame, to get at the screws into the back of the handle. The handle brackets were bent, so one handle was pointing up, and one was sagging. I had to change the position of the middle roller and the end pin because the top and bottom pins were at opposite ends on one set. The glass has a tempered glass etching on every panel, and OCD folks would freak out because the etchings are on the right of panel 1, on the right of panel 2, on the right of panel 3, and on the left of panel 4. I don't know if I can remove the frame from the glass to flip it or not. I will have to take some time to adjust the gaps, but I was expecting to have to fiddle with them a little.
Had everything been perfect except for minor adjustments to get the gaps equal, they would have been worth the $276. With the quality control issues, I feel they are priced a bit high. I guess I should feel lucky to find a brand name for a 22-year-old fireplace that never had doors.
