I bought this whiteboard sticker for my apartment a few weeks ago and I have to say I like it a lot! It doesn't blow any minds away, but it's definitely a good edition to any room. It's convenient, the setup takes virtually no time and overall looks pretty nice! It functions as any other whiteboard would, except it's incredibly more portable.

One downside I would have to say though is that it's not very wide, so unless you plan using this as a traditional whiteboard you should be fine. Otherwise, you might need to layer them very carefully, otherwise it won't be very big. For something like refrigerator doors this shouldn't be an issue, but for a wall it might be a problem. However, for a closet door like mine it works great!
