Expected issues with roll out, but found customer support to be responsive & excellent overall. Dealt with same contact the whole time! How many companies can you say that about? Light feature works fine, press & hold upper button. Connect issues have cleared up, have weeks of tracking data on the app now. Graphs are a nice touch. Getting messages, notifications and goal notifications too. Sync issue still lags sometimes, but checking back on the app, it syncs, w/out data loss. No, it is not an Apple or Samsung smart watch, but i didn’t want one of those. I wanted what the PowerWatch offered, especially having a device I did not have to CHARGE with simple operation & durable. Thanks Matrix!
