This SMS gateway hardware crashes randomly and requires regular reboots, which is a problem for a device used to send critical alerts via SMS. The lack of a screen makes it impossible to determine the moment when it failed or stopped working normally. Performance is poor (most likely due to the fact that it's running on a Raspberry compute). It's completely proprietary, which limits you to the existing features and limited web configuration. You can't build on that, which is extremely disappointing. Not recommended.
