I've had the Surge maybe 7-8 months ago..and I have to say it was very disappointing. At least at the time, the GPS couldn't be used for anything other than running, so unless you were an avid runner, the Charge HR was functionally similar but a lot less expensive. Lastly, at least up until March 2015, the Surge basically had no smart-watch features besides SMS and Phone call notifications. The touch screen is nice and all, but it's also not useful.
