I purchased these due to the price  - which was very nice. My initial thoughts were that the tiles seemed flimsy. HOWEVER, after installing them they look great. I watched a video tutorial and it stated that the tiles could be re-positioned. This is true BUT it will peel off the dry wall. 

I worked top to bottom, left to right. I recommend pre-cutting edges at once. this seemed to save time, measure twice and cut once! 

If you have an area that you want to dress up on a budget, i recommend this product.
