FIRST I want to let you know that I received this item from a discount website. It is not free for me and I do NOT need to leave a review to get a discount. My mom bought this particular brand of magnetic tiles (Discovery Kids) for my nephew a few years ago and also gifted my kids a set a year or two ago. We all LOVE them. They're not directional like some I've played with, meaning they connect every side to every side. They have enough magnetic attraction that you can build fairly tall structures. We (my family or my brother) had no problem with the magnets coming out or the tiles falling apart in any way. Obviously we like them a lot as this is the second set for my family and my mom also bought a third set (Christmas gifts). They are expensive at full price but no more expensive than other sets especially for the quality. I highly recommend them! By the way, my delivery was also fast, WITHOUT Prime.
