Nice product. Someone else said that it took a long time to install because of poor instructions. Don't understand this, it was obvious, instructions not necessary other than that provided and the picture on the box. However, there is a clear quality control problem with the manufacturer. Upon delivery I found that there were 2 x right hand brackets instead of one of each. I contacted Hahn, who were very helpful, but it took over a week for the replacement left hand bracket to arrive, and then, the new bracket was a tad longer than the original, so a bit of tweeking was required to make it fit square on the wall, also the screw holes were not countersunk, as were the originals, and so the screws would not sit flush. I, therefore, had the countersink the holes myself. Good design, good quality materials, poor quality control. Now its on the wall its great.
The magnificent Stephen Hawkings mind, which leaves most of us struggling after a few words, has done a great job here. Much easier to read and understand than the original, but you still have to be able to concentrate. A fascinating book.A Briefer History of Time
