Very average, useless
Sorry guys but the app keeps crashing whenever i manually insert the serial number of my robot (there is no qr code to scan on my device so i go manual). I have never moved forward than that step, really dissapointing and definatelly not worth the extra money than the standard s300 ( i recently bought the s300i). Totally not worth and i would like my money back. I tried reinstall the app, update it but nothing. Worthless, if only i knew i would not go forward and purchase the robot. Extremely poor. I use an iphone X 256GB
