I took this to our family vacation and we did this on the fridge during the downtimes. I live in St. Louis, but the rest of my family does not. They've visited several times, and this was a fun way to remind them of their visits, and get them to come back! I will say the pieces are quite thin, so take care when placing or removing. But they stick really well.I work magnetic puzzles on a cookie sheet.This was a gift for our 13-year-old granddaughter. She is not much for puzzles but thought she might like a map of her neighborhood.I immediately put every piece on my fridge. After sorting into sections of the city we quickly realized that its missing a ton of pieces. Im really mad about that. There was a foil seal to peel back on the top and mine was already peeled.i bought a new one. Not a used one.Accurate map, but quality of the map is ho hum. Pieces are bent, separating from maganits and some weren't punched properly.This was a topical gift. It didn't matter if they ever used it are acknowledged that I knew their interests and history.Pieces do not fit together well and come apart as you try to connect another piece.Los Angeles is a large city. This puzzle doesn’t capture all of LA. I expected Griffith Park, LA Zoo and the surrounding areas to be included. Northeast LA was excluded which was disappointing.Fun way to learn Boston prior to a visit.
