A lifetime warranty on the metal components, according to the research on our board. That covers the plates and the mechanism's metal parts, which are the pieces that matter for longevity. Plastic parts and cradles are usually covered for a shorter term, so check the current terms before you buy.

Keep the plates dry and the set off damp floors so the metal does not rust. Keep the cradle clear of dust and chalk so the plates seat cleanly. Always set the dumbbell fully in the cradle before twisting the handle, never force it, and check the plates are locked before each lift.
