My son (3) accepts the "time eating" hourglasses super as the timeout for various things (tightening, waiting, ...). We have "to Hopp, now you hurry but" not nearly as much discussion and. It makes it a lot of fun to turn the hourglasses itself (and even me sometimes to put a time limit). For durability, I can not say anything yet. Would she at any time buy and also get us a great set to!
