It’s amazing to see what my 3 year old builds with these. They had them at his daycare and he loved them so much we bought a set for home!It’s so much fun to see the different ideas and designs he comes up with on his own. It’s crazy that he comes up with completely new ideas all the time, plus as often as they get smashed down and dropped they have mostly held up to all the abuse. We plan on buying him another set for Christmas so you know we love them!Be careful, you children could get quite a pinch if their little fingers get in between the magnetic parts. With that said, though, my children love these!Got these on Prime Day for about $50 which is about half the price of Magna-Tiles.The first thing I did is confirm that they do work seamlessly with our existing Magna-Tiles.Some reviews mentioned the magnets not being as strong and they are correct. I was able to consistently get a square of these tiles (orange in the picture) to support the weight of 3 more squares (sometimes 4), whereas with the Magna-Tiles (green in the picture) I could consistently get a square to support the weight of 4 more squares (sometimes 5).Another review mentioned them being lighter, but they are actually about 1% heavier than my Magna-Tiles.They seem like decent quality and my child has not complained yet about them being inferior to the Magna-Tiles.GIft for 4 year old granddaughter- she loved them!!Bought these as a new toy to help keep them off the carpet during potty training. Worked wonders. It kept the twins occupied for multiple hours each day over potty training weekend.The magnets are not quite strong enough for the blocks to stand up without counter support.It’s expensive but it’s pretty cool to have and build with ..Lots and lots of fun!Would we prefer connectix tiles, yes, can we afford them, no. These make having decent magnetic tiles attainable, they're brilliant, granted they're not as strong as connectix and the colours aren't quite as pretty but they're still pretty darn good, played with daily and the creation possibilities are endless.I bought these for my preschoolers. Had them a week now. They have absolutely loved them. Good amount as well. My only problem is that I found a good portion of them have started to crack and break already. I would say it was the children misusing them, but they only play with them on the carpet and I've bought other brands that have lasted over a year of repeated use by over 60+ preschoolers, and held up better.Most of the tiles arrived broken and unable to be used so had to bin! Be careful with younger childrenI saw good reviews so decided to buy. We have the play mags and these are really weak compared. Every time my boy tries to make something it collapses and leaves him feeling very disappointed. For that reason I don't reccomend...better stick to the quality ones.
