We found these, and loved them so much that not only did we buy one of each set, we became resellers.
They are 100% compatible with LEGO brand blocks. As far as quality goes, they are as good as you can get – we collect the name brand, and would not sell these if we felt they were a poor value. There is a sample page from one of the manuals pictured. The graphics are stickers, not printed blocks, and the set comes in a bag instead of a box.
The Sky Wolf is 8" long x 10" wide x 4.5" high. It is 238 pieces and comes with two minifigs.
