I bought this for my eleven year old daughter's room -- for the back of the door. Was difficult to find those types of mirrors locally. On Amazon, full length mirrors were fairly pricey most likely due to the shipping size. I stumbled upon these in my search and after reading the reviews decided they should work well.They do work well. The tiles come well packaged in separate tiles which you can "assemble" in way you want. I assembled them in a row vertically and the seems are not really a factor in terms of obstructing view or being distracting. The "image" is good with clear reflection and no odd distorted effects. They all arrived intact and had no damage.These are actual glass tiles not the plastic mirror-like material you often see with behind-the-door mirrors. As a result, I was also concerned with their weight as I didn't want to risk heavy glass panels falling in my daughter's room. These are actually fairly thin -- which worked well for my application. They come with more than enough double sided mounting tape and they hold very well. No concern whatsoever that these will fall.If you are looking for some easily mountable glass panels -- especially for the back of the door -- these will work well for you. Price was fair and quality seems very good. As for longevity, they are in place firmly and I don't see anyone disturbing them on the back of the door so I anticipate it will last a long time.
