There is a one-year warranty on the Osmo base, and most all other physical pieces are replaced free of charge, within reason (with the exception of the Creative Board, markers, and 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 email@example.com for assistance with that process. While we do not replace lost bases, we do sell them on our site, www.playosmo.com, for $19 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 a request online for replacements.
