To start off, I've hung wallpaper for years, and looking at it, I liked the design, and was happy with the amount of glue that was on the prepasted vinyl.  That being said, the only problem was, it is VERY fragile to hang, and once it is wet, you have to be VERY careful hanging it, because it will tear VERY easily.  I actually only had two small tears, but I wouldn't recommend it to someone who has never hung wallpaper.  Also, it does hide "some" imperfections, but but larger imperfections it does not hide.
