Me gusta mucho porque siempre tiene encuestas disponibles.
Me gusta mucho porque siempre tiene encuestas y aunque no califiques en algunas te dan algunas monedas y te redirigen a otras más, tiene excelentes premios y el canje es sencillo, seguro y eficiente.

Muy buena
Muy buena, posee encuestas de todo tipo y permite recolectar buenos premios. Mejorar las encuestas que dicen 5000 monedas, en las cuales respondes muchas preguntas y te van dando pocas monedas y después cierran la encuesta de la nada. Eso no es agradable!

Buenos premios
Hay que hacer varias encuestas para los premios pero no es difícil llegar, tiene buenos canjes que permiten ahorrar y llega a los pocos días de pedirlos. Seguiré haciendo más
