Purchased RPLIDAR A1 M8 from Revain in USA on 21st April. Unpacked and checked today, connected to a PC, started scanning and transferred data to a PC. But after five minutes of operation, the device stopped and does not work. I contacted SlamTech, the manufacturer. The manufacturer advised to contact Amazon for after-sales service. I want to know what warranty applies to this item. The sudden failure of the device looks like a defective product. When such errors occur, the credibility of the product is lost. Please return the warranty for this device.
