This was a heavy, well made sink.  It was easy to install.  The sink rests on the bolts, so I inserted small pieces of rubber tubing to separate the metal from the porcelain.  The only thing I did not like about this sink is that the bolt holes are on the bottom part of the back, rather than the upper part, which makes the sink top heavy.  I compensated by covering the back with silicon sealant before bolting to the wall.  Then I braced up the sink until the sealant dried.  This made for a solid, against the wall mount.
