Useless seller. Not trying to help in anyway. The product itself measures the temperature fine in the mobile app. But the remote function isn't working properly, and the email alert function doesn't work at all (it requires an email provider without SSL/TLS, and all normal email services require ssl/tls). The seller did nothing to help out. I reached the manufacturer directly and offered to solve the issue in the next app upgrade (will take a long time, though).
Product works to take temperature. But buy it to another seller. This one is useless if you need something. They don't reply my messages anymore. Not that they were any helpful before.
