Filters are good but app is useless – Filtrete Smart Review

The re-order on Amazon functionality doesn’t work and the filters lose the Bluetooth connection almost immediately. For a year the app just usually says “lost connection” and stays that way. So it’s really just a countdown timer to remind you to buy their overpriced filters - overpriced because they’ve added a Bluetooth functionality that doesn’t function.
