I tried eureka. All the surveys were always locked. Only thing you could do was the 1p a day. It was useless. The games only offered a penny a minute for the first 10 mins or so then it was a penny for 5 or 10 mins. Honestly I found it useless. Playing games for 6p an hour isn't for me.
Qmee seemed to disqualify the majority of surveys, which was a little annoying.
Up to know I'm having better results with ipsos I say. They pay a better rate. Or attapoll which I average a tenner a week, mainly do that in ad breaks. It has its issues, pay is low and you have to avoid the ones that seem to offer better rates for a few minutes survey then redirect you to another survey which is 4 times longer, but I just close them immediately.
You gov offer better rates but you don't get regular surveys and have to earn £50 before you can withdraw, which could take many months .I know you can earn more by linking bank accounts, but I'm not prepared to give them that access
I'm really liking shopmium atm. Its dead easy to use,pays really quickly and as long as you only buy stuff you would be buying anyway it's a no brainer .
In the last month I've had £40 from attapoll, £20 from ipsos and £25 from shopmium. It helps a little. Its going in a Christmas fund
