The positives: The walk sticker arrived in good time and was wrapped well. The person I spoke with from the sales team for advice was helpful; but I still wasn't convinced.
Negatives: The wall sticker was a map and it was quite a large one covering appox 2.5m by 1.5. It came in 2 pieces which you would have assumed; should align easily. However that was not the case! They were hard to match and had an overlap and a white boarder on each sticker; so trying to get the center of the map looking seamless where the two pieces joined was hard to achieve, resulting in a noticeable (for me) join! Not happy!
I wouldn't recommend anybody getting a detailed text map from here.
