Magnets are dangerous for children of they swallow them. Unless it is a magnet strip I would prefer buttons.

The magnets are well embedded in the clothes so there's little danger there.

The reality is it doesn't do much more or less than normal onesies but costs an insane amount more.

Also sticks to the side of the wash machine lol.

That sounds handy. Parent sticks the baby on the side of the washing machine and can now load it using two hands.
