The posts here so far represent my experiences as well. I am very selective now on which site I am on.
I am a member of SSI directly, and another very long standing GPT combined with a few survey sites directly, but now mostly active on SSI and CS, both are my top sites. CS allows you to cashout with a $6 minimum balance as a PREMIUM - even the standard balance is competitive compared to most surveys companies direct where you get paid after 4 to 8 weeks of processing and minimum cashouts of $25, $50 even $100 ! I get far more surveys done here than directly.
One disturbing fact however is that doing surveys through network sites you get the left overs / surplus samples of other surveys that did not quite finish on schedule, so a lot of the times you are off quota, don't qualify or get screened out in the middle or end of said surveys - something I did not experience that much back in the years and this trend seems to be increasing.
Despite all that my top earnings are now on ClixSense when it comes to surveys & tasks, and another site that starts by N and ends with X when it comes to winning cash prizes
But CS is my better choice when it comes to earnings, and it has even better rates and offers than the 18+ year old GPT I am on by as much a 25% better pay rate.....
Also what's good aside from money here is the support, so fast to respond and effective - honesty, no lies no deceit no narcissistic tendencies, no bots, no ponzi schemes, no expensive upgrades, no serial scamming and lasting 3 months and shutting down, no bux model, and no general sense of dictatorship and controlling people's opinion, mods are generally good here and only edit posts when necessary unlike many of the other sites I have seen !
More facts I like about CS - When a post is edited by a mod / staff it shows WHO edited and the reason, which shows integrity and honesty, unlike many of the other sites I have seen !
And last but not least, transparency and integrity - Here, this site does not hide behind the pretext of user privacy and makes available user stats who win prizes, makes available a full set of your referral statistics, no hiding names, no hiding stats, and a full set of your own personal statistics - you know exactly how many clixgrid chancse you clicked, how many total clicks, EVERYTHING you have done is documented. This is one of my biggest praise of any given site, full disclosure !
I think the BUX model tarnished the reputation of the PTC industry, because many people associate BUX with PTC when it is far from the truth. The BUX model was never meant to be a PTC one from the start...... So a lot of people are not joining good sites and going towards fast earnings of ponzi schemes, whilst overlooking the good sites.
There should be more sites like CS and more REAL PTCs out there - to once and for all exterminate all those ponzi bux sites that open and are copycat immitations or just wannabe (mostly wannabes) of successful sites but can't even get there if they tried !
