The system was easy to install and set up which is always a bonus. In operation there is a lag between sending a request and the data starting to flow. It is slight but noticable. It can be affected by weather and sometimes the modem locks up, requiring a reset but this is easily done and having spoken to people using a land-line connection, they experience the same problems. Overall we are very pleased with Europasat, backup has been good for the last three years and the cost the service has gone down as the data allowance has gone up. We have recommended the system to others and no one has come back with any complaints
