I absolutely love this wallpaper. It was easy enough to put in place but two people are needed at all times. The preglued paper worked for us, but in order to make it stick properly, we had to use a good amount of water (not just a light spray) and spray the wall as well. As soon as we started to wet the wall too, everything was easier. The pattern has a slight misalignment causing it to be aligned in one spot and not quite somewhere else despite it being straight. Not a big deal, the result is still stunning. Other recommendations is to use a moist cloth to flatten the wallpaper. The moisture help the paper to relax further and the cloth glides better than a hand. Push the air bubble diagonally all the way out. Have a small small roller for the sides. It made all the difference for us as they were peeling at first but the pressure of the roll is for even and strong.  Lastly, cut the overhang with an exacto when the paper has started to dry or it will tear. Great product!
