The lined 3 x 3 pads by Post-it are a lifesaver. They are conveniently sized, not too big and not too small. I like that there are lines so that I can keep things a little neater when making lists. The adhesive on the back does not stick particularly well to certain things, like doors, computer screens, or plastics; however, they do stick to other paper-type products well. They come in a variety of vibrant colors ranging from magenta to deep purple to the classic Post-it yellow. I have found myself using more and more of them on a daily basis. They are great for a quick reminder when walking out the door so that you minimize forgetting the kids backpack, the library book, or whatever you might need help in remembering. I am a little disappointed that there is not more recycled content in the post-its. I think that this would be a product that could easily be made with recycled goods. All in all, it's a product worth paying a little more for so that you can have the convenience.
