Yesterday 7.64$ arrived at my PayPal account from Clixsense. That proves that Clixsense is indeed a genuine paid to click page. It doesn't mean however that it is worth the time it takes to actually earn the money. I have been clicking daily since end of August and I only earned enough for half a grocery shopping trip.
My final note reviewing Clixsense is as such, it is genuine, but your time can be spent much, much better.
