I have worked with eTelllegen's team for over 4 years now as an intern to senior developer/manager positions. The support provided by their entire organization was outstanding! They always went out of there way to help me solve any issue that arose during my tenure at ETI. Their customer service skills were second-to-none too. There are no dislikes about this product or these people. If you need great communication skills - go through them first. You will not be disappointed! As mentioned above, they helped build several mobile applications including one which we won 1st prize from Google Playstore (Best New Game).
