Yes, it comes with a lifetime warranty.

REP will warranty these products from defects in material, functionality, and workmanship for the lifetime of the product. Lifetime warranty coverage ends when the product becomes unusable for reasons other than defects in material or workmanship. The warranty applies only to the original purchaser and is nontransferable.

While we've ensured the dumbbell is designed to withstand occasional drops without issue, even pro-style, fixed dumbbells can be broken with repeated drops and abuse. If you have to drop your adjustable dumbbell, we recommend dropping it as flat as possible, as edge drops will put the most stress on the dumbbell.

The lifetime warranty does not cover:

Wear and tear due to normal usage (e.g., scratches, dents, rust).

Any damage to any part resulting from abnormal/abusive use (consistent drops), negligence, lack of care, accidents (drops/dings), incorrect use and/or operation of the dumbbell as specified in the user manual by REP.
