I do other PTC/GPT sites, but I earned more on ClixSense in my first month than I've been able to on some of the others in six months. The offers and tasks are comparatively plentiful and pay well across the board, so there's a lot of value here. It's convenient, easy to maneuver and saves time to spend the majority of my time on one site and do what's here knowing I'll be paid and not in a month, or two, or more while they float my earnings and look for ways to deny me but in a few days and with no hassles and no pressure, pressure, pressure to invest in addition to what the site earns from my efforts. (Although I probably will, they've proven it's a good investment to make.)
Can't beat it.
