Do you offer refurbishment for products outside of the one-year warranty?

You are here:

We’re sorry, but at this time we do not have a refurbishment program for Cubelets or other products outside of the 1-Year Warranty period.

We offer a 1-Year Warranty on all of our products, whether you purchase through or through one of our approved vendors. If any Cubelet or MOSS component stops working, takes an unplanned swim in the pool, or gets chewed on by a bear within that year, Modular Robotics will refurbish or replace your robot block for you for free. (Shipping costs may apply.) Modular Robotics reserves the right to reject warranty items that have been intentionally abused.

If you have some older Cubelets that have stopped working then please contact our team at We can usually get some back in working order with a little remote troubleshooting. We also accept shipments of non-working products for recycling and proper disposal, which will earn you a discount on your next purchase!
