My daughter took good care of her aquadoodle, but after a few months of moderate use the frabric in the center (most used) portion of the board no longer responded to the pen. After repeated attempts to get a hold of customer service, they stated they only back thier product for 30 days.Dissapointed. Seems like a great idea, but didn't hold up well to even moderate use and vigilant care for spills etc.
