I have purchased 3 of the plain message board decals and 4 of the basic calendars. They cover almost every wall of my 2-room workplace. We are using the message boards for various lists and project management details. Even though we have sophisticated digital file sharing capabilities, nothing beats writing things down when you think of them, or having the visuals in front of you during team meetings. We have to watch that they aren't installed in areas that might have a lot of movement or stuff near it, as the dry erase marker can easily wipe off. We have some of them installed on doors. We are a non-profit organization and move locations every couple of years and I look forward to being able to move these with us to our next location. I highly recommend these products!
