Easy to use, even allows for passive data collection, nice map view, with overlay showing where already data is present etc. Very good alternative, only downside currently it is only possible to submit reports to one source at a time, while TowerCollector allows 2 sources (however AFAIK you can resubmit the reports if you manually change the submit url in the settings).
