Recent reviews

App is absolute bare minimum, just enough to function. Connects only with wifi from ET20 ET20 has severe problem when battery fully discharges. When connected to charger, design defect causes camera to be destroyed. Had not used it for a long time. Turned it on... nothing. connected to power. Camera worked, so I let it charge several hours until full. Connected with app, black screen. Research shows this is a known failure mode where the device destroys itself. ET20 is now trash.
