There is a one-year warranty on the Osmo bases only; most of the other physical pieces are replaced free of charge, within reason (with the exception of the MindRacers Hot Wheels cars, MindRacers launch pad, Creative Board, Yoobi markers, and Yoobi fuzzy pouch).
If you'd like to request a replacement Osmo base, you must send us your broken base (base + reflector) first. Please reach out to firstname.lastname@example.org for assistance with that process. While we do not replace lost bases, we sell them on our site PlayOsmo, for $29 USD.
We replace lost or broken game pieces and red reflectors free of charge, within reason. Click this link for details on how to submit an online request for replacements.
