Query: Quality lacking

I suppose I shouldn't be surprised due to the low price, but I was disappointed with the quality of this item.1. Sheets are VERY thin & tear easily.2. Almost impossible to get them on a wall without all sorts of creases, air bubbles, etc.3. Static charge doesn't hold up well. Mine were falling down after 2 days.4. This is especially true if you try to reposition a few times.Nice concept, good in a pinch, but not any sort of long term use due to the quality of the material.
