I love our vanity. It came in very well packaged and it fit our plumbing perfectly. The only issue I had was that I got sent the wrong vanity the first  time. While the first one was absolutely beautiful, it was too big for our powder room so we had to return it. 
Anyway, this one is not that heavy, but it feels that it will last. Another big brand store sells this same vanity for a lot more, so I was very happy I found the same one for a lot cheaper at Wayfair.
