I got this along with the 35 puzzle. They are both really enjoyable to solve as you can do them intuitively. Even non cubers would find it fun.
The magnets under each tile are medium strength so they don't ruin the experience (but strong enough so if you turn the puzzle upside down the tiles won't fall off)
Tip: for the last 2 rows, solve them vertically so 36 - 43 first then 37 - 44 :)))
