They've moved with them multiple times. 3 house moves in different cities/towns and many times throughout their current house! Though, to be fair, they used to laminate them in real wood. That said I've had some mac-tack $10 Ikea bookshelves (I bought 4!) for over 4 years and I've moved them once, taken them apart and put them back together multiple times with no problems . I store my entire mini library on those. All good. If you're careless with the connectors and screws then you're going to have a bad time. Definitely watch how much torque you put into any action. I also wouldn't treat them as a jungle gym. They won't compare to a dovetailed hardwood shelf mounted to studs, but they hold up alright with care.
