I’ve had the misfortune of having both my original POP and more recently my POP2 scanners go bad. Each time the Revopoint support people have been fantastic. I made a movie of the problem (eg. POP2 has stopped working - YouTube ) and sent it to firstname.lastname@example.org on 5/9/2022. A new unit was shipped from China on 5/12/2022. On 5/23/2022 I got the shipping label and instructions of how to send the defective unit back for analysis. I received a replacement unit this morning 5/26/2022. Even with COVID going on, the Revopoint team is getting things done. Thank you Olivia, Cassie, Agnes, and Ela Marie.
