Don't forget to register your R2 warranty online at: https://robo3d.com/register/ I believe under US law a company can't deny warranty because the owner failed to register their product, but it's a good idea to do so. There was some question a while back on Kickstarter as to warranty for Kickstarter units. After submitting the online form I received a reply acknowledging that I was registered. The form indicated a 2 year warranty for the R2. However the R2 spec page on the Robo website says 1 year. Don't know which is correct.
