Product review (3 stars): it works fine. No movement from the dryer on top so ...
The fit wasn't "perfect" for my W/D. I had to hammer out the lip a little bit to make it straighter. Originally, the bracket would not line up with holes to screw in on the dryer. The instructions say to just wiggle it around and move the washer around to make it fit, but that didn't work. Once the screw holes were lined up, it works fine. No movement from the dryer on top so far and feels very stable.
